SOT-23-5 PIN DESCRIPTIONS PIN NAME FUNCTION 1 GND Ground reference 2 GND Ground reference, device substrate, connect to ground. RESET Active-low output. RESET remains low while VCC is below the reset threshold voltage, and for 190 LM3722/LM3724 ms after VCC rises above the reset threshold voltage. 3 RESET Active-high output. RESET remains high while VCC is below the reset threshold, and for 190 ms LM3723 after VCC rises above the reset threshold. Active-low input. Reset is asserted whenever this pin is pulled low and remains asserted for 190 ms 4 MR after the MR pin goes high.
