AP2114HA-3.3TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

AP2114HA-3.3TRG1 from Diodes Incorporated, in a SOT-223. 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 Input supply voltage pin. Operating range 2.5V to 6.0V (6.5V absolute max). Bypass with 4.7µF ceramic capacitor. Must be applied before load current to prevent premature short-circuit protection activation.
2 GND power_in Device ground reference. Also serves as thermal path for the SOT-223 tab; tie to a copper pour for heat dissipation (θJA = 128 °C/W without heatsink).
3 VOUT power_out Regulated 3.3V output, 1A continuous. Accuracy ±1.5%. Requires 4.7µF ceramic, tantalum, or aluminum electrolytic output capacitor for stability. Internally discharged (~60Ω) when EN is pulled low on 8-pin variants.
