Shutdown control input. 4 ADJ Output voltage adjust terminal. 5 VOUT Regulated voltage output. Input Voltage Supply (VIN) 3.4 Output Voltage Adjust (ADJ) Connect unregulated input supply to the VIN pin. If there is a large distance between the input supply and the LDO regulator, some input capacitance is necessary for proper operation. A 1 F capacitor connected from VIN to ground is recommended for most applications. Output voltage setting is programmed with a resistor divider from VOUT to this input. A capacitor may also be added to this input to reduce output noise (see Section 4.2 "Output Capacitor"). 3.2 Connect the output load to VOUT of the LDO. Also connect the positive side of the LDO output capacitor as close as possible to the VOUT pin. Ground (GND) Connect the unregulated input supply ground return to GND. Also connect the negative side of the 1 F typical input decoupling capacitor close to GND and the negative side of the output capacitor C1 to GND. 3.3 3.5 Regulated Voltage Output (Vout) Shutdown Control Input (SHDN) The regulator is fully enabled when a logic high is applied to this input. The regulator enters shutdown when a logic low is applied to this input. During shutdown, output voltage falls to zero and supply current is reduced to 0.5 A (maximum). (c) 2007 Microchip Technology Inc. DS21353D-page 9 TC1070/TC1071/TC1187 4.0 DETAILED DESCRIPTION 4.1 The TC1070, TC1071 and TC1187 are adjustable output voltage regulators. (If a fixed version is desired, please see the TC1014/TC1015/TC1185 data sheet.) Unlike bipolar regulators, the TC1070, TC1071 and TC1187 supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0 mA to IOUTMAX operating load current range, (an important consideration in RTC and CMOS RAM battery back-up applications). Figure shows a typical application circuit. The regulator is enabled any time the shutdown input (SHDN) is at or above VIH, and shutdown (disabled) when SHDN is at or below VIL. SHDN may be controlled by a CMOS logic gate, or I/O port of a microcontroller. If the SHDN input is not required, it should be connected directly to the input supply. While in shutdown, supply current decreases to 0.05 A (typical), VOUT falls to zero volts. 3.0V Battery + 1 VIN + C1 1 F 2 3 VOUT 5 R1 470K GND SHDN +2.45V C2 + 1 F TC1070 TC1071 TC1187 ADJ 4 C3 100 pF to 0.01 F (Optional) R2 470K Shutdown Control (from Power Control Logic) FIGURE 4-1: DS21353D-page 10 Battery-Operated Supply Adjust Input The output voltage setting is determined by the values of R1 and R2 (Equation 4-1). The ohmic values of these resistors should be between 470K and 3M to minimize bleeder current. The output voltage setting is calculated using the following equation. EQUATION 4-1: VOUT = VREF x [ R1 +1 R2 ] The voltage adjustment range of the TC1070, TC1071 and TC1187 is from VREF to (VIN - 0.05V). If so desired, a small capacitor (10 pF to 0.01 F) may be added to the ADJ input to further reduce output noise. 4.2 Output Capacitor A 1 F (minimum) capacitor from VOUT to ground is recommended. The output capacitor should have an effective series resistance greater than 0.1 and less than 5.0, and a resonant frequency above 1 MHz. A 1 F capacitor should be connected from VIN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30C, solid tantalums are recommended for applications operating below -25C.) When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques. (c) 2007 Microchip Technology Inc. TC1070/TC1071/TC1187 5.0 THERMAL CONSIDERATIONS 5.1 Thermal Shutdown Integrated thermal protection circuitry shuts the regulator off when die temperature exceeds 160C. The regulator remains off until the die temperature drops to approximately 150C. 5.2 Equation 5-1 can be used in conjunction with Equation 4-2 to ensure regulator thermal operation is within limits. For example: Given: Power Dissipation The amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. The following equation is used to calculate worst-case actual power dissipation: EQUATION 5-1: = 3.0V 10% VOUTMIN = 2.7V - 2% ILOADMAX = 40 mA TJMAX = 125C TAMAX = 55C Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: PD (VINMAX - VOUTMIN)ILOADMAX = [(3.0 x 1.10) - (2.7 x .0.98)]40 x 10-3 P D (VINmax - VOUTmin)ILOADmax Where: PD VINMAX VOUTMIN ILOADMAX VINMAX = Worst-case actual power dissipation = Maximum voltage on VIN = Minimum regulator output voltage = Maximum output (load) current = 26.2 mW Maximum allowable power dissipation: PDMAX = (TJMAX - TAMAX) JA = (125 - 55) 220 = 318 mW The maximum allowable power dissipation (Equation 4-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (TJMAX) and the thermal resistance from junction-to-air (JA). The 5-Pin SOT-23 package has a JA of approximately 220 C/Watt. In this example, the TC1070 dissipates a maximum of 26.2 mW which is below the allowable limit of 318 mW. In a similar manner, Equation 5-1 and Equation 5-2 can be used to calculate maximum current and/or input voltage limits. EQUATION 5-2: 5.3 PDMAX = (TJMAX - TAMAX) JA where all terms are previously defined. (c) 2007 Microchip Technology Inc. Layout Considerations The primary path of heat conduction out of the package is via the package leads. Therefore, layouts having a ground plane, wide traces at the pads, and wide power supply bus lines combine to lower JA and therefore increase the maximum allowable power dissipation limit.

Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving.
