DESCRIPTION
The MP20042 is a dual-channel, micropower,
low noise, low dropout and high PSRR linear
regulator. The output voltage of MP20042
ranges from 1.2V to 5.0V and 1% accuracy by
operating from a +2.5V to +6.0V input. The
MP20042 can supply up to 200mA of load
current at each channel.
The MP20042 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
MP20042 features current limiting and over
temperature protection.
It is available in a 2mm x 2mm QFN8 package.
FEATURES
• Two LDOs in a 2mmx2mm QFN8 Package
• Up to 200mA Output Current (Per Channel)
• Dual Enable Pins Control Each Output
• 72dB PSRR at 1kHz
• 11μV
RMS Low Noise Output
• 110mV Dropout at 100mA Load
• Very Fast Transient Responses with Small
Output Capacitor
• Current Limiting and Thermal Protection
APPLICATIONS
• Cellular Phones
• Battery-powered Equipment
• Laptop, Notebook, and Palmtop Computers
• Hand-held Equipment
• Wireless LAN

Notes:
1) Exceeding these ratings may cause permanent damage to
the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P

)/ θ
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside its operating
conditions.
4) Measured on JESD51-7 4-layer board.
