AP2125K-3.0TRG1

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-23-5

AP2125K-3.0TRG1 from Diodes Incorporated, in a SOT-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 Input voltage pin; the recommended input range is VOUT+0.5V to 6V, with an absolute maximum of 6.5V.
2 GND power_in Ground reference pin for the regulator.
3 CE input Active-high enable input: logic high enables the regulator and logic low shuts it down, with a high threshold of at least 1.5V and a low threshold of at most 0.4V.
4 NC unconnected No internal connection; leave unconnected.
5 VOUT power_out Regulated output voltage pin, 3.0V fixed for this variant with ±2% accuracy.
