LP2951ACMMX-3.3

Texas Instruments · Linear Voltage Regulators (LDO) · VSSOP-8-0.65mm

LP2951ACMMX-3.3 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 for the LP2951ACMMX-3.3 (3.3 V option), which the datasheet ensures can deliver 100 mA output current.
2 SENSE input Output voltage sense input that is tied to OUT in the 8-pin test configuration.
3 SHUTDOWN input Disable device input, with electrical characteristics specified at VSHUTDOWN ≤ 0.8 V.
4 GND power_in Ground reference pin for the regulator.
5 ERROR output Error flag output that warns of output dropout (low output voltage).
6 VTAP output Internal resistor divider output, tied to FEEDBACK for the fixed-output test configuration.
7 FEEDBACK input Voltage feedback input with an absolute maximum range of −1.5 V to 30 V.
8 IN power_in Input supply voltage, with a recommended operating range of 2.3 V to 30 V and a 30 V maximum.
