AP2127K-3.0TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

AP2127K-3.0TRG1 from Diodes Incorporated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power input. Operating input voltage range 2.5V to 6V (absolute max 6.5V). Requires 1µF low-ESR ceramic bypass capacitor to GND.
2 GND power_in Device ground reference.
3 Shutdown input Active-low enable input (nSHDN). Drive >=1.5V to enable the regulator; drive <=0.5V to place the device in shutdown mode (Istandby ~0.1µA). Internal ~3MΩ pull-down resistance.
4 NC/ADJ unconnected No Connection for fixed-voltage versions (AP2127K-3.0 is a fixed 3.0V variant, so this pin is NC). On adjustable variants this pin is the VOUT feedback input (ADJ) for an external resistor divider.
5 VOUT power_out Regulated 3.0V power output, up to 300mA continuous (400mA typ current limit, 50mA short-circuit limit). Requires 1µF low-ESR ceramic output capacitor to GND. Auto-discharge MOSFET (~60Ω) pulls VOUT low when disabled.
