L99VR01 Block diagram and pins description PowerSSO-12 Pin name SO-8 pin Function pin
Watchdog refresh input. Wi 10 If the square wave frequency at this input pin is too low, a low pulse at RST pin is generated (just for L99VR01J). Reset output. RST 7 11 It is pulled down when output voltage goes below Vo_th or frequency at Wi is too low (just for L99VR01J). Leave floating if not used. Voltage regulator output. VO 8 12 Block to ground with a capacitor ≥ 3.3 µF (needed for regulator stability). TAB TAB Connected to ground
