MD5325-1 from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 GND power_in Ground / VSS reference pin. Common return for the LDO's internal reference, error amplifier, and pass transistor. Tie directly to the system ground plane via a single-point connection close to the input and output bypass capacitors.
2 VIN power_in Regulator input supply. Accepts up to 10 V continuous (12 V absolute max). Bypass to GND with CIN ≥ 1.0 µF placed as close to the pin as possible for stability and transient response.
3 VOUT power_out Regulated 2.5 V output (±2%), rated 500 mA typical with 1 A current limit. Requires an output capacitor CL ≥ 2.2 µF (tantalum) or ≥ 10 µF (aluminum electrolytic) between VOUT and GND for loop stability.
