Murata ceramic capacitors were used, GCM32ER71E106KA57 (10 mF, 25V, X7R, 1210), Circuit Description The NCV4276C is an integrated low dropout regulator that provides a regulated voltage at 400 mA to the output. It is enabled with an input to the inhibit pin. The regulator voltage is provided by a PNP pass transistor controlled by an error amplifier with a bandgap reference, which gives it the lowest possible dropout voltage. The output current capability is 400 mA, and the base drive quiescent current is controlled to prevent oversaturation when the input voltage is low or when the output is overloaded. The regulator is protected by both current limit and thermal shutdown. Thermal shutdown occurs above 150C to protect the IC during overloads and extreme ambient temperatures. GRM32ER71E226ME15 (22 mF, 25V, X7R, 1210). Calculating Bypass Capacitor If usage of low ESR ceramic capacitors is demand in case of Adjustable Regulator, connect the bypass capacitor Cb between Voltage Adjust pin and Q pin according to Applications circuit at Figure 4. Parallel combination of bypass capacitor Cb with the feedback resistor R1 contributes in the device transfer function as an additional zero and affects the device loop stability, therefore its value must be optimized. Attention to the Output Capacitor value and its ESR must be paid. See also Stability in High Speed Linear LDO Regulators Application Note, AND8037/D for more information. Optimal value of bypass capacitor is given by following expression Regulator The error amplifier compares the reference voltage to a sample of the output voltage (VQ) and drives the base of a PNP series pass transistor via a buffer. The reference is a bandgap design to give it a temperature-stable output. Saturation control of the PNP is a function of the load current and input voltage. Oversaturation of the output power device is prevented, and quiescent current in the ground pin is minimized. See Figure 4, Test Circuit, for circuit element nomenclature illustration. Cb + 2 p 1 fz R1 @ (F) where R1 = the upper feedback resistor fz = the frequency of the zero added into the device transfer function by R1 and Cb external components. Set the R1 resistor according to output voltage requirement. Chose the fz with regard on the output capacitance CQ, refer to the table below. Regulator Stability Considerations The input capacitors (CI1 and CI2) are necessary to stabilize the input impedance to avoid voltage line influences. Using a resistor of approximately 1.0 W in series with CI2 can stop potential oscillations caused by stray inductance and capacitance. The output capacitor helps determine three main characteristics of a linear regulator: startup delay, load transient response and loop stability. The capacitor value and type should be based on cost, availability, size and temperature constraints. The aluminum electrolytic capacitor is the least expensive solution, but, if the circuit operates at low temperatures (-25C to -40C), both the value and ESR of the capacitor will vary considerably. The capacitor manufacturer's data sheet usually provides this information. The value for the output capacitor CQ, shown in Figure 3, should work for most applications; see also Figures 5 to 8 for output stability at various load and Output Capacitor ESR conditions. Stable region of ESR in Figures 5 to 8 shows ESR values at which the LDO output voltage does not have any permanent oscillations at any dynamic changes of output load current. Marginal ESR is the value at which the output voltage waving is fully damped during four periods after the load change and no oscillation is further observable. ESR characteristics were measured with ceramic capacitors and additional series resistors to emulate ESR. Low duty cycle pulse load current technique has been used to maintain junction temperature close to ambient temperature. CQ (mF) 10 22 47 fz Range (kHz) 16 - 18 11 - 18 8 - 18 Ceramic capacitors and its part numbers listed bellow have been used as low ESR output capacitors CQ from the table above to define the frequency ranges of additional zero required for stability. GCM32ER71E106KA57 (10 mF, 25V, X7R, 1210) GRM32ER71E226ME15 (22 mF, 25V, X7R, 1210) GRM32ER61C476ME15 (47 mF, 16 V, X5R, 1210) Inhibit Input The inhibit pin is used to turn the regulator on or off. By holding the pin down to a voltage less than 1.8 V, the output of the regulator will be turned off. When the voltage on the Inhibit pin is greater than 2.8 V, the output of the regulator will be enabled to power its output to the regulated output voltage. The inhibit pin may be connected directly to the input pin to give constant enable to the output regulator. Setting the Output Voltage (Adjustable Version) The output voltage range of the adjustable version can be set between 2.5 V and 20 V. This is accomplished with an external resistor divider feeding back the voltage to the IC back to the error amplifier by the voltage adjust pin VA. www.onsemi.com 11 NCV4276C In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heatsink will be required. The internal reference voltage is set to a temperature stable reference of 2.5 V. The output voltage is calculated from the following formula. Ignoring the bias current into the VA pin: VI Use R2 < 50 k to avoid significant voltage output errors due to VA bias current. Connecting VA directly to Q without R1 and R2 creates an output voltage of 2.5 V. Designers should consider the tolerance of R1 and R2 during the design phase. The input voltage range for operation (pin 1) of the adjustable version is between (VQ + 0.5 V) and 40 V. Internal bias requirements dictate a minimum input voltage of 4.5 V. The dropout voltage for output voltages less than 4.0 V is (4.5 V - VQ). PD(max) + [VI(max) * VQ(min)] IQ(max) VQ Iq Figure 29. Single Output Regulator with Key Performance Parameters Labeled Heatsinks A heatsink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air.

RqJC appears in the package section of the data sheet. Like RqJA, it too is a function of package type. RqCS and RqSA are functions of the package type, heatsink and the interface between them. These values appear in data sheets of heatsink manufacturers. Thermal, mounting, and heatsinking considerations are discussed in the ON Semiconductor application note AN1040/D. Once the value of PD(max) is known, the maximum permissible value of RqJA can be calculated: o T RqJA + 150 C * A PD (3) (2) The value of RqJA can then be compared with those in the package section of the data sheet. Those packages with RqJA less than the calculated value in Equation 2 will keep the die temperature below 150C. www.onsemi.com 12 110 RqJA, THERMAL RESISTANCE (C/W) RqJA, THERMAL RESISTANCE (C/W) NCV4276C 100 90 80 1 oz 70 2 oz 60 50 40 0 100 200 300 400 500 600 700 800 80 75 70 65 60 1 oz 55 50 2 oz 45 40 35 30 0 COPPER SPREADER AREA (mm2) 100 200 300 400 500 600 700 800 COPPER SPREADER AREA (mm2) Figure 30.
