AP2127N-1.8TRG1

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

AP2127N-1.8TRG1 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; the datasheet lists it as the ground reference for the regulator, with CIN and COUT returned to this pin.
2 VOUT power_out Regulated output; the fixed-voltage output (1.8 V for AP2127N-1.8TRG1), supplying up to 300 mA with COUT of at least 1 µF ceramic (X7R or X5R) recommended.
3 VIN power_in Power input; the recommended input voltage range is 2.5 V to 6 V, and a 1 µF ceramic capacitor is recommended between VIN and GND.
