Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

MD8233 from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 pin; connect to the input and output capacitor returns with low-impedance wiring.
2 VOUT power_out 3.3V regulated output (±3%) rated 150mA with 300mA typical current limit; must not exceed VIN+0.3V, and needs an output capacitor of 2.2µF or more.
3 VIN power_in Supply input rated up to 40V for regulation (absolute maximum 45V); needs an input capacitor of 1.0µF or more.
