AP2127N-3.0TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

AP2127N-3.0TRG1 from Diodes Incorporated, in a SOT-23. 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 GND power_in Ground pin for the regulator; the input and output capacitors must be returned to this pin, and the input supply is specified at 2.5V to 6V.
2 VOUT power_out Regulated 3.0V fixed output (AP2127N-3.0 is a fixed-output version rated up to 300mA); place the 1µF low-ESR ceramic output capacitor as close as possible to VOUT and GND.
3 VIN power_in Power input with a recommended operating range of 2.5V to 6V; a 1µF ceramic capacitor should be placed as close as possible between VIN and GND.
