Description
AP7344
DUAL 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE
Pin Assignments
The AP7344 is a Dual low dropout regulator with high output voltage
accuracy, low RDSON, high PSRR, low output noise and low quiescent
current. This regulator is based on a CMOS process.
Each of regulators includes a voltage reference, error amplifier,
current limit circuit and an enable input to turn on/ off output. With the
integrated resistor network fixed output voltage versions can be
delivered.
With its low power consumption and line and load transient response,
the AP7344 is well suited for low power handheld communication
equipment.
The AP7344 is packaged in X2-DFN1612-8 package and allows for
smallest footprint and dense PCB layout.

ESR vs. Output Current
Ceramic type output capacitor is recommended for this series; however, the other output capacitors with low ESR also can be used. The relations
between IOUT (Output Current) and ESR of an output capacitor are shown below. The stable region is marked as the hatched area in the graph.
Measurement conditions: Frequency Band: 10Hz to 2MHz, Temperature: −40°C to +85°C.
