[AK1110AEU]
AK1110AEU
2ch Output, Ultra High PSRR, Ultra Low Noise LDO Regulator
1. General Description
The AK1110AEU is a dual output low dropout linear regulator with ON/OFF control. Each output can
supply 100mA and 200mA load current. The AK1110AEU is an integrated circuit achieving excellent ripple
rejection and low output noise characteristics with silicon monolithic bipolar structure. In addition, over
current and thermal protections are integrated. It is especially well suited for noise sensitive applications.
The AK1110AEU is housed in a small and thin type PLP10-2725 package with an exposed pad. It is
designed for space saving requiring systems.
