POWER MONITORING OUTPUT,
5.5 V INPUT, 100 mA CMOS VOLTAGE REGULATOR
WITH 0.5 μA SUPER LOW CURRENT CONSUMPTION
Rev.1.1_00
The S-1740/1741 Series, developed using CMOS technology, is a positive voltage regulator with a power monitoring 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 power monitoring output is prepared in the S-1740/1741 Series. The power monitoring output is a
function that divides the input voltage (VIN) of the regulator into VIN/2 or VIN/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.
