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 (Top View) NEW PRODUCT 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
output voltage. The over temperature sensing is for each channel with
all 4 channel being disabled during a temperature fault condition. The
device 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.
With its low power consumption and line and load transient response,
the AP7348 is well suited for low power handheld communication
equipment.
The AP7348 is provided in the X1-DFN1612-8 (Type B) package
allowing for a small footprint and a dense PCB layout. Features Low VIN and Wide VIN Range: 1.7V to 5.25V Each Channel Output Current: 300mA
