AP2125KS-1.8TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

AP2125KS-1.8TRG1 from Diodes Incorporated, in a SC-70-5. 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 Input voltage pin; recommended range VOUT+0.5V to 6V, absolute maximum 6.5V.
2 GND power_in Ground.
3 CE input Active high enable input; logic high (≥1.5V) enables the output, logic low (≤0.4V) shuts the regulator down.
4 NC unconnected No connection.
5 VOUT power_out Regulated output voltage, 1.8V fixed for this version, with 300mA minimum output current.
