MST52L33BTE

MST · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

MST52L33BTE from MST, in a SOT-23. 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 System ground pin.
2 VOUT power_out Output pin of the fixed-voltage LDO; the output current is rated up to 150 mA and output voltage accuracy is ±2% of VOUTNOM.
3 VIN power_in Input pin; the input voltage range is 3 V to 24 V, with an absolute maximum VIN to GND of 30 V.
