DESCRIPTION

The MP20041 is a dual-channel, micropower,

ultra low noise, low dropout and high PSRR

linear regulator. The output voltage of MP20041

ranges from 1.2V to 3.6V in 100mV increments

and 1% accuracy by operating from a +2.5V to

+6.0V input. The MP20041 can supply up to

300mA of load current at each channel.

The MP20041 uses an internal PMOS as the

pass element, which consumes 114μA supply

current (both LDOs on) at no load condition.

The EN1 and EN2 pins control each output

respectively. When both channels shutdown

simultaneously, the chip will be turned off and

consume nearly zero operation current which is

suitable

for

battery-power

devices.

The

MP20041 features current limit and over

temperature protection.

It is available in a 2mm x 2mm TQFN8 package.

FEATURES

 Wide Operating Voltage Ranges: 2.5V to 6V

 Two LDOs in a 2mmx2mm TQFN8 Package

 Up to 300mA Output Current (Per Channel)

 Dual Enable Pins Control Each Output

 72dB PSRR at 10kHz

 11μVRMS Ultra Low Noise Output with No

Noise Bypass Capacitor Required

 73mV Dropout at 100mA Load

 Very Fast Line/Load Transient Responses

with Small Input/Output Capacitor

 Current Limit and Thermal Protection

APPLICATIONS

 Cellular Phones

 Battery-powered Equipment

 Laptop, Notebook, and Palmtop Computers

 Hand-held Equipment

 Wireless LAN
