These devices are capable of supplying 150 mA of output current with a dropout of 115 mV (TPS77133, TPS77233). Quiescent current is 92 A at full load dropping down to 1 A when device is disabled. These devices are optimized to be stable with a wide range of output capacitors including low ESR ceramic (10 F) or low capacitance (1 F) tantalum capacitors. These devices have extremely low noise output performance (55 Vrms) without using any added filter capacitors. TPS771xx and TPS772xx are designed to have fast transient response for larger load current changes. 200 IO = 150 mA 150 100 IO = 10 mA 50 IO = 0 A 0 -50 -40 0 40 80 120 TJ - Junction Temperature - C 160 The TPS771xx or TPS772xx is offered in 1.5 V, 1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5.0 V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The TPS771xx and TPS772xx families are available in 8-pin MSOP (DGK) packages. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 115 mV at an output current of 150 mA for 3.3 volt option) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 92 A over the full range of output current, 0 mA to 150 mA). These two key specifications yield a significant improvement in operating life for battery-powered systems.

POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 1 TPS77101/115/118/127/128/133/150 WITH RESET OUTPUT TPS77201/215/218/227/228/233/250 WITH POWER GOOD OUTPUT 150-mA LDO REGULATORS WITH 8-PIN MSOP PACKAGING SLVS225D - FEBRUARY 2000 - REVISED OCTOBER 2000 description (continued) The device is enabled when the EN pin is connected to a low-level input voltage. This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 A at TJ = 25C. The TPS771xx features an integrated power-on reset, commonly used as a supply voltage supervisor (SVS) or reset output voltage. The RESET output of the TPS771xx initiates a reset in DSP, microcomputer or microprocessor systems at power up and in the event of an undervoltage condition. An internal comparator in the TPS771xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. When OUT reaches 95% of its regulated voltage, RESET will go to a high-impedance state after a 220 ms delay. RESET will go to low-impedance state when OUT is pulled below 95% (i.e. over load condition) of its regulated voltage. For the TPS772xx, the power good terminal (PG) is an active high output, which can be used to implement a power-on reset or a low-battery indicator. An internal comparator in the TPS772xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. When OUT falls below 82% of its regulated voltage, PG will go to a low-impedance state. PG will go to a high-impedance state when OUT is above 82% of its regulated voltage.

When EN goes to logic low, then the device will be enabled. power good (PG) (TPS772xx) The PG terminal is an open drain, active high output that indicates the status of Vout (output of the LDO). When Vout reaches 82% of the regulated voltage, PG will go to a high-impedance state. It will go to a low-impedance state when Vout falls below 82% (i.e. over load condition) of the regulated voltage. The open drain output of the PG terminal requires a pullup resistor. sense (SENSE) The SENSE terminal of the fixed-output options must be connected to the regulator output, and the connection should be as short as possible. Internally, SENSE connects to a high-impedance wide-bandwidth amplifier through a resistor-divider network and noise pickup feeds through to the regulator output. It is essential to route the SENSE connection in such a way to minimize/avoid noise pickup. Adding RC networks between the SENSE terminal and Vout to filter noise is not recommended because it may cause the regulator to oscillate. feedback (FB) FB is an input terminal used for the adjustable-output options and must be connected to an external feedback resistor divider. The FB connection should be as short as possible. It is essential to route it in such a way to minimize/avoid noise pickup.

A higher-capacitance capacitor may be necessary if large (hundreds of milliamps) load transients with fast rise times are anticipated. Most low noise LDOs require an external capacitor to further reduce noise. This will impact the cost and board space. The TPS771xx and TPS772xx have very low noise specification requirements without using any external components. Like all low dropout regulators, the TPS771xx or TPS772xx requires an output capacitor connected between OUT (output of the LDO) and GND (signal ground) to stabilize the internal control loop. The minimum recommended capacitance value is 1 F provided the ESR meets the requirement in Figures 19 and 21. In addition, a low-ESR capacitor can be used if the capacitance is at least 10 F and the ESR meets the requirements in Figures 18 and 20. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described previously. Ceramic capacitors have different types of dielectric material with each exhibiting different temperature and voltage variation. The most common types are X5R, X7R, Y5U, Z5U, and NPO. The NPO type ceramic type capacitors are generally the most stable over temperature. However, the X5R and X7R are also relatively stable over temperature (with the X7R being the more stable of the two) and are therefore acceptable to use. The Y5U and Z5U types provide high capacitance in a small geometry, but exhibit large variations over temperature; therefore, the Y5U and Z5U are not generally recommended for use on this LDO. Independent of which type of capacitor is used, one must make certain that at the worst case condition the capacitance/ESR meets the requirement specified in Figures 18 - 21. 16 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 TPS77101/115/118/127/128/133/150 WITH RESET OUTPUT TPS77201/215/218/227/228/233/250 WITH POWER GOOD OUTPUT 150-mA LDO REGULATORS WITH 8-PIN MSOP PACKAGING SLVS225D - FEBRUARY 2000 - REVISED OCTOBER 2000 APPLICATION INFORMATION Figure 22 shows the output capacitor and its parasitic impedances in a typical LDO output stage. IO LDO - VESR RESR + + VI RLOAD VO - CO Figure 22. LDO Output Stage With Parasitic Resistances ESR and ESL In steady state (dc state condition), the load current is supplied by the LDO (solid arrow) and the voltage across the capacitor is the same as the output voltage (VCout = Vout). This means no current is flowing into the Cout branch. If Iout suddenly increases (transient condition), the following occurs: D The LDO is not able to supply the sudden current need due to its response time (t1 in Figure 23). Therefore, capacitor Cout provides the current for the new load condition (dashed arrow). Cout now acts like a battery with an internal resistance, ESR. Depending on the current demand at the output, a voltage drop will occur at RESR. This voltage is shown as VESR in Figure 22. D When Cout is conducting current to the load, initial voltage at the load will be Vout = VCout - VESR. Due to the discharge of Cout, the output voltage Vout will drop continuously until the response time t1 of the LDO is reached and the LDO will resume supplying the load. From this point, the output voltage starts rising again until it reaches the regulated voltage. This period is shown as t2 in Figure 23. The figure also shows the impact of different ESRs on the output voltage. The left brackets show different levels of ESRs where number 1 displays the lowest and number 3 displays the highest ESR. From above, the following conclusions can be drawn: D The higher the ESR, the larger the droop at the beginning of load transient. D The smaller the output capacitor, the faster the discharge time and the bigger the voltage droop during the LDO response period.

Current is conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be appropriate. The TPS771xx or TPS772xx also features internal current limiting and thermal protection. During normal operation, the TPS771xx or TPS772xx limits output current to approximately 0.9 A. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds 150C(typ), thermal-protection circuitry shuts it down. Once the device has cooled below 130C(typ), regulator operation resumes. power dissipation and junction temperature Specified regulator operation is assured to a junction temperature of 125C; the maximum junction temperature should be restricted to 125C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than or equal to PD(max). The maximum-power-dissipation limit is determined using the following equation: P D(max) T max * T A + J R qJA Where: TJmax is the maximum allowable junction temperature. RJA is the thermal resistance junction-to-ambient for the package, i.e., 266.2C/W for the 8-terminal MSOP with no airflow. TA is the ambient temperature. The regulator dissipation is calculated using: P D + V *V I O I O Power dissipation resulting from quiescent current is negligible.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
