NCP115AMX300TCG from onsemi, in a XDFN-4-EP(1x1). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated output voltage pin (3.0 V nominal for this OPN). A ceramic capacitor with a minimum value of 1 µF is required from this pin to GND for stability. Rated for up to 300 mA output current with typical dropout of 215 mV @ VOUT = 3.3 V, 300 mA. |
| 2 | GND | power_in | Power supply ground reference for the device. Also serves as the thermal return path; the exposed pad on the XDFN4 package should be soldered to the GND copper plane for effective heat removal. |
| 3 | EN | input | Enable input (active high). Driving EN above 0.9 V turns on the regulator; driving EN below 0.4 V puts the regulator into shutdown (IDIS typ. 0.01 µA). Absolute max VEN = 6 V; typical EN pin input current 0.3 µA at VEN = 5.5 V. |
| 4 | IN | power_in | Input supply pin. Operating input voltage range 1.7 V to 5.5 V (absolute max 6 V). A small ceramic input capacitor (1 µF typical) from IN to GND is required for stability and transient performance. |
| EPAD | EPAD | power_in | Exposed thermal pad on the bottom of the XDFN4 package. Must be connected directly to the GND pin and soldered to a large ground copper plane to allow effective heat removal (RθJA = 208 °C/W for XDFN4 1x1 mm). |
