HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION
S-87X Series
Seiko Instruments Inc.

3. Power Supply for Lithium-Ion Battery Pack
When the lithium-ion battery goes down to the overdischarge voltage, the built-in voltage detector powers OFF the voltage
regulator, and at the same time it transmits the RESET signal to the microcomputer. R1, C1, R2 and C2 are attached to
eliminate the voltage exceeding the absolute maximum ratings of charger. C3 is attached to give a delay and to release the
RESET signal after power supply voltage for microcomputer(V
OUT
) rises high enough.
Notes
DO NOT apply a ripple voltage of the conditions below to V
IN
pin.
When connecting the voltage regulator output pin to another power supply, insert a diode to protect the IC.
