LP2951CN

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

LP2951CN from Texas Instruments, in a PDIP-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 OUT power_out Regulated output voltage; in dual-supply systems where the output sees loads returned to a negative supply, the output should be diode-clamped to ground.
2 SENSE input Output voltage sense input, which the 8-pin test conditions tie to OUT; the datasheet gives an absolute input voltage range of -0.3 V to 30 V for the SHUTDOWN, ERROR and IN class of pins, and ESD rating of ±1500 V for this pin.
3 SHUTDOWN input Logic-compatible shutdown input that disables the device; the electrical characteristics are specified with VSHUTDOWN ≤ 0.8 V and the absolute maximum input voltage is -0.3 V to 30 V.
4 GROUND power_in Ground reference pin for the regulator.
5 ERROR output Error flag output that warns of low output voltage (dropout), with an absolute maximum voltage of -0.3 V to 30 V.
6 VTAP output Internal resistor divider tap, which the 8-pin test conditions tie to FEEDBACK.
7 FEEDBACK input Voltage feedback input with an absolute input voltage range of -1.5 V to 30 V; the 8-pin test conditions tie it to VTAP.
8 IN power_in Input supply voltage, specified from 2.3 V to 30 V with an absolute maximum of 30 V.
