MP20249

Dual, Ultra-Low Noise, High PSRR

200mA Linear Regulator

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP20249 is a dual-channel, ultra-low noise,

low dropout and high PSRR linear regulator.

Fixed output voltage options are available

between 1.2V to 3.3V with 1% accuracy by

operating from a +2.3V to +6.0V input. It is

designed to deliver up to 200mA of load current

at each channel. Dropout voltage is only 75mV at

full load. The MP20249 uses internal

PMOSFETS as pass elements, which consume

125µA supply current (both LDOs on) at no load

condition. With new innovative design techniques,

the MP20249 can achieve an output voltage

noise as low as 16µVRMS without using a

bypass capacitor at each channel. The MP20249

is designed and optimized to work with small-

value, low-cost ceramic capacitors, making it

ideal for applications with space-constraints. It

typically requires only 1µF of output capacitance

for stability with any load at each channel.

APPLICATIONS

•

Cellular Mobile Phones

Digital Cameras

Handheld and Battery-powered Equipment

Wireless LAN

The EN1 and EN2 pins control each output

respectively. When both channels shutdown

simultaneously, the chip is turned off and

consumes nearly zero operation current, which is

suitable for battery-power devices. The MP20249

features current limit and over-temperature

protection.

The MP20249 also has an output discharge

function that controls the quick discharging of the

output capacitor.

It is available in a miniature 6-ball WLCSP

package.
