REG101UA-A

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

REG101UA-A from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output; pin 1 and pin 2 must both be connected. Source of output current limited by foldback current limit (typ 170 mA).
2 VOUT power_out Regulated output; pin 1 and pin 2 must both be connected.
3 NR/Adjust passive For REG101-A, this is the voltage-setting resistor pin (reference 1.267 V typ, adjust pin current 0.2 µA typ, 1 µA max, absolute maximum voltage -0.3 V to 6.0 V).
4 GND power_in Ground pin for the regulator.
5 Enable input Enable input: output is enabled when VENABLE is at least 1.8 V and disabled when VENABLE is 0.5 V or less; absolute maximum is -0.3 V to VIN.
6 NC unconnected No internal connection.
7 VIN power_in Supply input; pin 7 and pin 8 must both be connected, with operating input range 1.8 V to 10 V and absolute maximum 12 V.
8 VIN power_in Supply input; pin 7 and pin 8 must both be connected, with operating input range 1.8 V to 10 V and absolute maximum 12 V.
