Analog Devices · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-23-5

ADP151AUJZ-3.3-R7 from Analog Devices, in a TSOT-23-5. 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 VIN power_in Regulator input supply; bypass VIN to GND with a 1 µF or greater capacitor. Input voltage range is 2.2 V to 5.5 V.
2 GND power_in Ground reference for the regulator.
3 EN input Enable input; drive high to turn the regulator on and low to turn it off, and connect to VIN for automatic startup. EN absolute maximum range is −0.3 V to +6.5 V to GND.
4 NC unconnected No connect; not connected internally.
5 VOUT power_out Regulated output voltage; bypass VOUT to GND with a 1 µF or greater capacitor.
