# NCP699SN33T1G

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

NCP699SN33T1G 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, rated 2.1 to 6.0 V. |
| 2 | Gnd | power_in | Power supply ground. |
| 3 | Enable | input | Pulling this input low disables the device into low-power standby (threshold high ≥0.95 V, low ≤0.3 V); connect to Vin if unused. |
| 4 | N/C | unconnected | No internal connection. |
| 5 | Vout | power_out | Regulated output voltage (3.3 V for this NCP699SN33T1G variant), up to 150 mA. |
