AP7340 150mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description Pin Assignments The AP7340 is a low dropout regulator with high output voltage accuracy, low R , high PSRR, low output noise and low quiescent DSON current. This regulator is based on a CMOS process. The AP7340 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 AP7340 is well suited for low power handheld communication equipment. The AP7340 is packaged in an X2-DFN1010-4 package and allows for smallest footprint and dense PCB layout.

See AP7340 Pin Descriptions PIN No Pin Name Function X2-DFN1010-4 V 1 Power Output Pin OUT GND 2 Ground Enable Pin EN 3 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 V 4 Power Input Pin IN In PCB layout, it is preferred to use large copper area to cover this pad for better thermal dissipation, Thermal PAD then connect this area to GND or leave it open.

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 +25C . The JEDEC High-K board design used to derive this data is a 2in. x 2in. multi-layer board with 1oz. internal power and ground planes and 2oz. copper traces on the top and bottom of the board.
