NCP115AMX105TCG 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 1.05 V output pin (300 mA max). A ceramic capacitor with minimum value of 1 uF is required from this pin to GND to assure stability. Current limit typ. 600 mA; short-circuit protected. |
| 2 | GND | power_in | Power supply ground reference. Should be tied to the ground plane; the exposed pad (EPAD, on XDFN4) must also be soldered to this ground for effective heat removal. |
| 3 | EN | input | Enable input. Driving EN above 0.9 V (V_EN_HI) turns the regulator on; driving EN below 0.4 V (V_EN_LO) puts the device into shutdown mode. Input current typ. 0.3 uA at V_EN = 5.5 V. Absolute max -0.3 V to 6 V. |
| 4 | IN | power_in | Unregulated input supply, 1.7 V to 5.5 V (absolute max 6 V). A small ceramic capacitor (>= 1 uF) is required from this pin to ground to assure stability. |
| 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 enable effective heat removal (R_theta_JA = 208 degC/W with 645 mm^2 Cu area). |
