Overview - S-87x series

High Withstand-Voltage Voltage Regulator with Reset Function S-87x series

The S-87x is a series of low-power high withstand-voltage regulators with a reset function, which integrates high-precision voltage detection and voltage regulation circuits on a single chip. The S-87x series has higher withstand-voltage characteristic and higher accuracy of detection voltage and output voltage, µ2.4% respectively. The S-87x series has also lineups for lithium-ion battery packs.
