This is an LDO voltage regulator that can output 5V / 1.5A. Comparing with other linear voltage regulator, it has very low voltage drop (about 0.35V with full load).
It could be soldered on the back of Witty Pi 3 Mini (footprint already exists on PCB), to get wider input voltage range.
- Input Voltage: Up to 26V
- Output Voltage: 5V
- Output Current: Up to 1.5A
- Package: TO-252-2(DPAK)
