Diodes Incorporated announced a 4-channel low dropout regulator AP7348 with high output voltage accuracy, high PSRR, low output noise and low quiescent current.
Each of the 4 LDO outputs are capable of 300 mA of current. Sub-system power requirements may change dynamically, and a large temporary current may be needed from one of the LDOs.
The AP7348 has two enable inputs with EN1 controlling both VOUT1 and VOUT3 leaving VOUT2 and VOUT4 to be controlled by EN2. During disable, the two associated channels will discharge.
The AP7348 is available in 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V and 3.6 V fixed output voltage versions.
It is available in a X1-DFN1612-8 (Type B) package.
