Please contact each Web shop for details such as availability of online samples.


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.


Accuracy of output voltage
±2.4%, 2.6V to 5.8V (0.1V step)
Accuracy of detection voltage
±2.4%(For the S-87xxxxF series, the release voltage ±1.1%), 2.1V to 11.3V (0.1V step)
Low I/O voltage difference
0.15V typ. at IOUT=30mA, VOUT=5.0V, 0.45V typ. at IOUT=30 mA, VOUT=3.0V
Low current consumption
Operation: 8 µA max.
Power off: 3.5 µA max. (Available for the S-87xxxxC/E/G series)
