# NCP502SN36T1G

**onsemi** · Linear Voltage Regulators (LDO) · TSOP-5

NCP502SN36T1G from onsemi, in a TSOP-5. 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 | Vin | power_in | Positive power supply input voltage, with a maximum rating of 12 V. |
| 2 | GND | power_in | Power supply ground. |
| 3 | Enable | input | Pulling this input low disables the device into low-power standby; for the NCP502 the enable threshold is 1.3 V high and 0.3 V low, and if the function is unused it should be connected to Vin. |
| 4 | N/C | unconnected | No internal connection. |
| 5 | Vout | power_out | Regulated output voltage (3.6 V nominal for this variant). |
