HIGH RIPPLE-REJECTION AND LOW DROPOUT
CMOS VOLTAGE REGULATOR
S-L2980 Series
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 shutdown
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.
