AP2205-33Y-13

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

AP2205-33Y-13 from Diodes Incorporated, in a SOT-89. 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 Unregulated supply input voltage. Operating range 2.3V to 24V; absolute maximum 36V. Recommended 1.0µF ceramic input capacitor (CIN) to GND close to the pin.
2 GND power_in Device ground reference. The substrate/exposed pad of the SOT89 package should be connected to GND or left open (per Note 4 on page 1).
3 VOUT power_out Regulated 3.3V output (fixed version, -33 option). Delivers up to 200mA (150mA when VOUT ≤ 1.8V). Requires a 2.2µF ceramic output capacitor (COUT) to GND for stability; compatible with low-ESR ceramic caps.
