AP2204RA-5.0TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

AP2204RA-5.0TRG1 from Diodes Incorporated, in a SOT-89. 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 GND power_in Ground reference pin for the RA variant; the datasheet gives no electrical limit for it beyond being the ground return.
2 VIN power_in Input voltage with recommended operating range 2.3V to 24V and absolute maximum supply input voltage 38V; for the RA variant this pin is also the substrate/exposed pad, which should be connected to VIN or left open.
3 VOUT power_out Regulated output voltage (5.0V for this fixed version), with minimum rated output current IOUT(max) of 150mA and absolute maximum output current of 250mA.
