Low Noise, 1A, Linear Regulator EV Board
The EV20045DN-00A evaluation board demonstrates the performance of MP20045, a low noise and low dropout linear regulator. It operates from a 2.5V to 5.5V input voltage and the output voltage can be set externally which ranges from 1.5V to 5V.
The EV20045DN-00A can supply up to 1A of load current, and features current limiting, over temperature protection and power-good status.
An internal PMOS pass element is used to allow a low 110uA ground current, marking the MP20045 suitable for battery-power devices.

The MP2004 is a dual-channel, low noise, low dropout and high PSRR linear regulator. The output voltage of MP2004 ranges from 1.2V to 5V and 1% accuracy by operating from a +2.5V to +6.0V input. The MP2004 can supply up to 200mA of load current at each channel. The MP2004 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 MP2004 features current limiting and over temperature protection.
