User pain point solution
Battery voltage drop caused by equipment crash → 1.8V continuous regulated output (3.7V → 1.8V throughout the regulated)
traditional DCDC interference sensor signal → 15mV ripple + 2.4MHz high frequency away from the ADC sampling band
small size equipment space constraints → 17.4mm × 26.2mm + vertical welding to save space
User's Frequently Asked Questions
Q1: Why does it consume power when no load?
Power saving mode is not enabled! Short the PS pad, or remove the LED (power consumption from 50μA → 1μA)
Q2: How to output non-standard voltage such as 4.0V?
Disconnect all jumpers and solder the ADJ resistor according to the formula:

R2 = (180K × (4.0×0.5 - 1)) - R1 (Example: R2=36K when R1=0Ω)
Q3: Input 5V output 3.3V is buck or boost?
Automatic switching! Buck when input＞output, Boost when input＜output.
