NCP115AMX280TCG 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 2.8 V output pin (fixed by the '280' option). Requires a ceramic capacitor of at least 1 uF from this pin to GND for stability. Rated for up to 300 mA continuous, with typical dropout of 250 mV at 300 mA. |
| 2 | GND | power_in | Power supply ground and reference return. The exposed pad must be tied to this pin. |
| 3 | EN | input | Active-high enable input. V_EN > 0.9 V turns the regulator on; V_EN < 0.4 V puts it into shutdown (I_DIS ~0.01 uA typ). Absolute max -0.3 V to 6 V; typical input current 0.3 uA at V_EN = 5.5 V. Do not leave floating. |
| 4 | IN | power_in | Unregulated input supply, 1.7 V to 5.5 V operating (absolute max 6 V). A small (>=1 uF) ceramic capacitor from IN to GND is required for stability. |
| EPAD | EPAD | power_in | Exposed thermal pad on the underside of the XDFN4 package. Must be soldered directly to the GND copper plane for effective heat removal (theta_JA = 208 C/W on 645 mm^2 Cu). |
