Overview - S-L2980 series

High Ripple Rejection and 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.
