HIGH RIPPLE-REJECTION AND LOW DROPOUT
CMOS VOLTAGE REGULATOR
Rev.5.1
_02
The S-L2980 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and
low current consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and a large output current. A ON/OFF
circuit ensures long battery life.
Various types of output capacitors can be used in the S-L2980 Series compared with the conventional CMOS
voltage regulators. A small ceramic capacitor can also be used.
