HIGH RIPPLE-REJECTION LOW DROPOUT
CMOS VOLTAGE REGULATOR WITH RESET FUNCTION
© ABLIC Inc., 2004-2015 Rev.3.1_02
1
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
current.
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.

*2. In the S-1701D to S-1701F, S-1701K to S-1701M, and S-1701U to S-1701W types (that detect output
voltage), a reset signal may be output due to the under shoot of the output voltage when the input voltage or
load current changes transiently. Therefore, set the detection voltage after sufficient evaluation using actual
devices.
