LP2951ACMM

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSSOP-8-0.65mm

LP2951ACMM from Texas Instruments, in a VSSOP-8-0.65mm. 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 OUT output Regulated output voltage of the LP2951-N; the electrical characteristics are specified with CL = 1 µF for 5-V versions and 2.2 µF for 3-V and 3.3-V versions.
2 SENSE input Output voltage sense input, which the datasheet specifies tied to OUT in the 8-pin test conditions.
3 SHUTDOWN input Logic-compatible shutdown input that enables or disables the regulator, with the 8-pin test conditions specifying VSHUTDOWN ≤ 0.8 V.
4 GND power_in Ground reference pin for the regulator; the datasheet recommends a wide ground return connection close to the input and output capacitors.
5 ERROR output Error flag output that warns of a low output voltage (such as falling input battery voltage) and may be used for power-on reset.
6 VTAP output Internal resistor divider tap, which the 8-pin test conditions specify tied to FEEDBACK.
7 FEEDBACK input Voltage feedback input for programming the output from 1.24 V to 29 V; absolute maximum input voltage range is -1.5 V to 30 V.
8 IN power_in Input supply voltage, with a recommended range of 2.3 V to 30 V and an absolute maximum of 30 V.
