REG101UA-5

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

REG101UA-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; pin 1 and pin 2 must both be connected, and the REG101-5 output is 5.0V.
2 VOUT power_out Regulated output; pin 1 and pin 2 must both be connected, and the REG101-5 output is 5.0V.
3 NR/Adjust passive Noise reduction capacitor pin (CNR, 0.01µF used for the 23µVrms noise figure) on fixed-voltage models; it is the voltage-setting resistor pin only on the REG101-A adjustable version.
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, with an absolute maximum of VIN.
6 NC unconnected Labeled NC (no connection) in the pin configuration; the datasheet gives no electrical function for this pin.
7 VIN power_in Supply input; pin 7 and pin 8 must both be connected, 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, with an operating input range of 1.8V to 10V and an absolute maximum of 12V.
