AP2139AK-3.0TRG1

Diodes Incorporated · New Arrivals · SOT-23-5

AP2139AK-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, 2.5V to 6.0V recommended operating range (6.6V absolute maximum), requires a 1µF input capacitor.
2 GND power_in Ground.
3 CE input Active high enable input; logic high (VIH min 1.2V) enables the output, logic low (VIL max 0.3V) puts the device in shutdown.
4 NC unconnected No connection.
5 VOUT power_out Regulated output voltage (3.0V fixed for this variant), up to 250mA, requires more than 1µF output capacitance with ESR 0.01Ω to 100Ω.
