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.

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.
