Pin Name
Pin Number
Function
SOT26 U-DFN2018-6
OUT 1 5, 6
Voltage output pin. This is the pin to the P-channel MOSFET drain connection. Bypass to ground
through a 0.1uF capacitor.
GND 2, 5 4 Ground.
EN 3 3 Enable input, active high
IN 4, 6 1, 2
Voltage input pin. This is the pin to the P-channel MOSFET source. Bypass to ground through a
1µF capacitor.
PAD 7 Thermal pad. Suggest connecting to ground plane to get better heat dissipation.
