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. |
