HIGH RIPPLE-REJECTION CMOS
LOW DROPOUT VOLTAGE REGULATOR
S-L2980 Series
The S-L2980 series is a low dropout voltage regulator
designed for use in battery powered devices and
developed using CMOS technology. On-chip low on-
resistance transistor can provide low dropout voltage and
large output current. A power-off switch ensures long
battery life.
Various types of output capacitors can be used in the
S-L2980 series compared with the former CMOS voltage
regulators. A small ceramic capacitor can also be used.
