Full load temperature rise: 40℃
Static current: 0.85 mA
Load regulation: ± 1%
Voltage regulation: ± 0.5%
Dynamic response speed: 5% 200uS
Output short circuit protection: Yes, but do not short-circuit for a long time
Input reverse polarity protection: None, input reverse polarity protection diode
Enable control: Yes, working at high level, stop working at low level, high level is around 2-5V, low level is about 0V.
The default input with internal pull-up to the positive electrode.
Output: welding / pin header
Welding hole spacing: 2.54 mm
The default output voltage is adjustable. If you need fixed output voltage, use a knife to cut the circuit of "ADJ" in the back of the PCB board, then connect the pad with solder at the voltage you need.
