DESCRIPTION

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.

It is available in a small 6-pin TSOT23 package.

FEATURES

• Two LDOs in a TSOT23-6 Package

• 69dB PSRR (100Hz)

• 110mV Dropout at 100mA Load

• Very Fast Transient Responses with Small

Output Capacitor

• Current Limiting and Thermal Protection

APPLICATIONS

• Cellular Phones

• Laptop PCs

• Hand-held Equipment

• Netbook Computing
