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, ±2.4% respectively. The S-87X Series has
also lineups for lithium-ion battery packs.
T

Note
In the S-87XXXXB/S-87XXXXG Series, When the output voltage of the voltage regulator is close to the detection
voltage of the voltage detector, the transient response of the voltage regulator may cause false detection. Please take
transient response into account when deciding voltages.
