LP2951-02YM-TR

Microchip Tech · Power Management Specialized - PMIC · SOIC-8

LP2951-02YM-TR from Microchip Tech, in a SOIC-8. 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 VOUT power_out Regulated voltage output, guaranteed at 100 mA with current limiting (typically 160 mA) and requiring a 1.0 μF (or greater) capacitor to ground for stability.
2 SENSE input Output voltage sense input, tied to Pin 1 (VOUT) for 5V pin-strapped operation.
3 SHDN input Logic-compatible shutdown input that switches the regulator on and off.
4 GND power_in Ground terminal.
5 ERROR output Open-collector error output that goes low when the output falls about 5% out of regulation, requires an external pull-up resistor (100 kΩ to 1 MΩ suggested), and is rated to sink 400 μA.
6 5V TAP passive Internal resistor divider tap for 5V output; connect to Pin 7 (FB) for 5V operation.
7 FB input Voltage feedback input with 1.235 V nominal reference and nominal 20 nA feedback bias current; used with external resistors to program the output from 1.24 V to 29 V.
8 VIN power_in Unregulated supply voltage input; a 0.1 μF capacitor from input to ground is recommended if more than 10 inches of wire or a battery is used as the input.
