LP2950G-50-S08-R

UTC Unisonic Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8

LP2950G-50-S08-R from UTC Unisonic Tech, 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 voltage pin (5.0V fixed for the -50 version, VOUT ±2% accuracy).
2 NC unconnected No internal connection.
3 SHUTDOWN input Logic-controlled shutdown input; low (≤0.70V) regulator ON, high (≥2.0V) regulator OFF, rated -0.3 to +30V.
4 GND power_in Ground.
5 ERROR output Active-low error comparator output flagging output out of regulation; output low voltage 280mV max at IOL=400µA, leakage 1µA max at 30V.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 INPUT power_in Unregulated supply input, absolute maximum -0.3 to +30V.
