The Future of Analog IC Technology
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.
