AP7348 4 CHANNEL 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description Pin Assignments
The AP7348 is a 4 channel low dropout regulator with high output voltage accuracy, low RDS(ON), high PSRR, low output noise and low

quiescent current. This regulator is based on a CMOS process. The AP7348 includes two voltage references, and four channels with each having an error amplifier, foldback current limiting, a discharge

circuit and an independent resistor network to determine the fixed
T
output voltage. The over temperature sensing is for each channel with
C
all 4 channel being disabled during a temperature fault condition. The
U
device has two enable inputs with EN1 controlling both VOUT1 and
D
VOUT3 leaving VOUT2 and VOUT4 to be controlled by EN2. During
O
disable the two associated channels will discharge.
