Fast Transient Response, 2A Linear Regulator EV Board
The EV20046DN-00A evaluation board demonstrates the performance of MP20046, a low noise, low dropout and high PSRR linear regulator. It operates from a 2.7V to 5.5V input voltage and the output voltage is preset internally which ranges from 1.5V to 3.3V.
The EV20046DN-00A can supply up to 2A 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 75μA ground current at full load, and drops down to 1μA when the device is disabled, making the MP20046 suitable for battery-power devices.

Monolithic ICGET THIS IC
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.
