LP2951-5.0DRG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8

LP2951-5.0DRG from HANSCHIP semiconductor, in a SOP-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 OUTPUT power_out Regulated output; tie to SENSE for fixed 5 V output, rated for 100 mA with a minimum 1 µF output capacitor for 5-V versions.
2 SENSE input Remote sense input; tie to OUTPUT for the fixed 5 V output, or leave open when using an external resistor divider for adjustable output.
3 SHUTDOWN input Logic-compatible shutdown input; low (≤0.7 V) turns the regulator on and high (≥2 V) turns it off, with a 30 V maximum input.
4 GND power_in Ground.
5 ERROR output Open-collector error output that goes low when VOUT drops about 6% below nominal, needs an external pullup of 100 kΩ to 1 MΩ, sinks up to 400 µA, and may be left open if unused.
6 VTAP output Internal resistor divider tap; tie to FEEDBACK for the fixed output voltage, or leave open for adjustable operation.
7 FEEDBACK input Error amplifier feedback input compared against the 1.235 V reference; tie to VTAP for fixed output or to an external resistor divider for 1.235 V to 30 V adjustable output.
8 INPUT power_in Unregulated supply input, operating up to 30 V continuous (absolute maximum 30 V).
