REG102UA-5

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

REG102UA-5 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 voltage; pin 1 and pin 2 must both be connected, per datasheet note (2).
2 VOUT power_out Regulated output voltage; pin 1 and pin 2 must both be connected, per datasheet note (2).
3 NR/Adjust passive For REG102-A (adjustable) this is the voltage-setting resistor pin; for all other models it is the noise reduction capacitor pin (CNR, 0.01µF used in the datasheet conditions), with an absolute maximum pin voltage of -0.3V to 6.0V.
4 GND power_in Ground reference pin for the regulator.
5 Enable input Enable input: output is enabled when VENABLE is at least 1.8V and disabled when VENABLE is 0.5V or lower; the absolute maximum enable input voltage is -0.3V to VIN.
6 NC unconnected No internal connection.
7 VIN power_in Supply input; pin 7 and pin 8 must both be connected, per datasheet note (3), with an operating input range of 1.8V to 10V and an absolute maximum of 12V.
8 VIN power_in Supply input; pin 7 and pin 8 must both be connected, per datasheet note (3), with an operating input range of 1.8V to 10V and an absolute maximum of 12V.
