ADVANCED INFORMATION AP7341 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description The AP7341 is a 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. The AP7341 includes a voltage reference, error amplifier, current limit circuit and an enable input to turn it on and off. With the integrated resistor network fixed output voltage versions can be delivered. With its low power consumption and line and load transient response the AP7341 is well suited for low power handheld communication equipment. The AP7341 is packaged in an X2-DFN1010-4 package and allows for smallest footprint and dense PCB layout.

This pin should be driven either high or low and must not be floating. Driving this pin high enables the regulator, while pulling it low puts the regulator into shutdown mode Power Input pin In PCB layout, prefer to use large copper area to cover this pad for better thermal dissipation, then connect this area to GND or leave it open. However do not use it as GND electrode function alone. Absolute Maximum Ratings (Note 4) (@TA = +25°C, unless otherwise specified.)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. b). Ratings apply to ambient temperature at 25°C . The JEDEC High-K board design used to derive this data was a 2 inch x 2 inch multilayer board with 1ounce internal power and ground planes and 2-ounce copper traces on the top and bottom of the board.
