HIGH RIPPLE-REJECTION LOW DROPOUT
CMOS VOLTAGE REGULATOR WITH RESET FUNCTION
The S-1701 Series, developed based on CMOS technology, is a voltage regulator with a reset function and integrates a
high-accuracy voltage detector with on-chip delay circuit and a positive voltage regulator with a low dropout voltage and high
output voltage on one chip.
The S-1701 Series is available in many types according to the selection of the voltage detector block of the voltage detector,
including a SENSE pin input product. A built-in low on-resistance transistor provides a low dropout voltage and large output
Small ceramic capacitors are available and an external capacitor for delay is needless. Small SOT-23-5 and SOT-89-5
packages realize high-density mounting.
