Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AP2205-25W5-7 from Diodes Incorporated, in a SOT-25. 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. Operates from 2.3V to 24V (absolute maximum 36V). Bypass to GND with a 1.0µF ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference. All bypass and load-return currents flow through this pin.
3 EN input Active-high enable input. VIH >= 2.0V turns the regulator on; VIL <= 0.4V places the device in shutdown (ISTD typ 0.01µA). Enable pin current typ 3µA at VEN = VOUT+1V. Absolute maximum 36V; do not leave floating.
4 ADJ/NC unconnected On the fixed-output AP2205-25W5-7 (2.5V) variant this pin is Not Connected internally (NC). On the adjustable variant the same pin is the ADJ feedback input to the internal error amplifier (VREF = 1.24V). For the -25W5 fixed part, leave floating or tie to GND.
5 VOUT power_out Regulated 2.5V output (±2%). Max continuous IOUT = 200mA (150mA for VOUT <= 1.8V variants), typical IOUT(MAX) 250mA. Requires >= 2.2µF ceramic output capacitor for stability; compatible with low-ESR ceramics.
