AP7348 Low Noise LDO with Enable

Diodes Incorporated AP7348 Low Noise Low Dropout (LDO) with Enable features high output voltage accuracy, low R_DS(ON), high PSRR, and low quiescent current. This regulator determines the output voltage using two voltage references and four channels, each with an error amplifier, foldback current limiting, and a discharge circuit. The AP7348 LDO offers two enable inputs with EN1 controlling both V_OUT1 and V_OUT3, leaving V_OUT2 and V_OUT4 to be controlled by EN2. The two associated channels will discharge during turn-off. This LDO is based on a CMOS process, consumes low power, and is well suited for low-power handheld communication equipment. Typical applications include smartphones, tablets, RF supply, cameras, portable video, portable media player, wireless adapter, and wireless communication.
