MIC2954-02WS-TR

Microchip Tech · Linear Voltage Regulators (LDO) · SOT-223-3

MIC2954-02WS-TR from Microchip Tech, in a SOT-223-3. 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 IN power_in Supply input; the datasheet's operating range is +2.0V to +30V, with absolute maximum −20V to +60V (positive transients limited to <10ms and <1% duty cycle).
2 GND power_in Ground; the SOT-223 ground is listed as pin 2 together with the TAB, which is the same ground connection.
3 OUT power_out Regulator output of the fixed 5V MIC2954-02 version, guaranteed to 250mA output current.
