NCP711ASNADJT1G 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 | IN | power_in | Power supply input pin, recommended input voltage range 2.7 V to 18 V. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable input pin (high - enabled, low - disabled); if connected to IN or left unconnected (no pull-up resistor required) the device is enabled. |
| 4 | ADJ | input | Adjust input pin on the ADJ version (NCP711ASNADJT1G); connect it to the output resistor divider or directly to the OUT pin, with a 1.2 V reference. |
| 5 | OUT | power_out | LDO output pin, up to 100 mA output current. |
