P7340

150mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

The AP7340 is low dropout regulator with high output voltage

accuracy, low R

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 a X2-DFN1010-4 package and allows for

smallest footprint and dense PCB layout.

Functional Block Diagram

Function

Enable pin. 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

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.

Note: 4. a). 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 1-ounce internal power and ground planes and 2-ounce copper traces on the top and bottom of the board.

Notes: 5. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.

6. Quiescent current is defined here is the difference in current between the input and the output.

7. Short circuit current is measured with V

8. This specification is guaranteed by design.

9. To make sure lowest environment noise minimizes the influence on noise measurement.
