LP2954IMX

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8-150mil

LP2954IMX from Texas Instruments, in a SOIC-8-150mil. 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 power_out Regulated output voltage (adjustable from 1.23 V to 29 V via external divider to FEEDBACK). Requires an output capacitor (≥2.2 μF typ) for loop stability. Sources up to 250 mA.
2 SENSE input Output voltage remote sense. Connects internally to the output regulation feedback path so that IR drops in the OUT trace can be compensated by wiring SENSE at the load.
3 SHUTDOWN input Active-low logic shutdown input. Pulling this pin low disables the regulator and puts the device into a low-current standby state; tie high (or leave floating with a pull-up) for normal operation.
4 GND power_in Device ground reference. Carries the quiescent current (~120 μA typ) plus internal control-circuit return.
5 ERROR output Active-low error/power-good flag. Asserts (pulled low) when the regulator output falls out of regulation (e.g. during dropout), warning downstream logic before the rail collapses.
6 5V TAP output Internal resistor divider tap that provides a preset 5-V feedback point. Tie to FEEDBACK to configure the adjustable part for a fixed 5-V output without any external resistors.
7 FEEDBACK input Voltage feedback input to the internal error amplifier (internal reference ~1.23 V). Set the output voltage via an external R1/R2 divider from OUT to GND, tapped into FEEDBACK; or strap FEEDBACK to the 5V TAP pin for a fixed 5-V output.
8 IN power_in Unregulated input supply, -20 V to +30 V absolute maximum. Reverse-battery protected. Requires an input capacitor for stability; dropout is ~60 mV at light load and ~470 mV at 250 mA.
