LP2951ACMX

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

LP2951ACMX from Texas Instruments, in a SOIC-8. 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 OUT output Regulated output voltage, fixed 3V/3.3V/5V or programmable 1.24V to 29V with 100mA ensured output current.
2 SENSE input Output voltage sense input for internal feedback divider; tie to OUT for fixed voltage operation.
3 SHUTDOWN input Logic-compatible disable input; regulator enables below 0.7V and disables above 1.3V.
4 GND power_in Ground reference terminal, common connection point for return paths.
5 ERROR output Open-collector error flag output; pulls low when output drops 75-95mV below 1.235V reference threshold.
6 VTAP output Internal 1.235V reference voltage divider tap; tie to FEEDBACK pin for fixed voltage versions.
7 FEEDBACK input Voltage feedback input for programmable output regulation; -20nA typical bias current.
8 IN power_in Positive power supply input voltage, 2.3V to 30V absolute maximum range.
