5.5 V INPUT, 100 mA VOLTAGE REGULATOR
WITH SUPPLY VOLTAGE DIVIDED OUTPUT
Rev.1.3
_00
The S-1740/1741 Series, developed using CMOS technology, is a positive voltage regulator with the supply voltage divided
output, which features super low current consumption and low dropout voltage.
The regulator block has low current consumption of 0.35
μA
typ. and high-accuracy output voltage of
±1.0%.
The function of the supply voltage divided output is prepared in the S-1740/1741 Series. The supply voltage divided output is
a function that divides the input voltage (V
IN
) of the regulator into V
IN
/2 or V
IN
/3 and outputs the voltage. For example, this
function makes it possible that the IC connects to a low voltage microcontroller A/D converter directly and the microcontroller
monitors a battery voltage.
