HIGH RIPPLE-REJECTION LOW DRO POUT
CMOS VOLTAGE REGULATOR WITH RESET FUNCTION
© Seiko Instruments Inc., 2004-2010 Rev.3.0_00
Seiko Instruments Inc. 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 pos itive v olt age regul ator with a l o w drop out voltag e and h ig h
output voltage on one chi p.
The S-1701 Series is availabl e in many type s according to the se lectio n of the voltage detector block of t he voltage detector,
including a SENSE pin input product. A built-in low on-resistance transist or provides a low dropout volt age 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.
Features

*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 undershoot of the output voltage when the input volt age or
load current changes transiently. Therefore, set the detection voltage after sufficient evaluation using actual
devices.
