AP2202R-3.3TRE1

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-89-3

AP2202R-3.3TRE1 from Diodes Incorporated, in a SOT-89-3. 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 VOUT power_out Regulated output voltage; an output capacitor of at least 1.0µF is required to prevent oscillation when CBYP is unused.
2 GND power_in Ground, which is also the TAB (heat-sink tab) on the SOT-89 package.
3 VIN power_in Input voltage; the datasheet recommends VIN of VOUT+0.5V to 13.2V and a 1µF minimum input capacitor between VIN and GND.
