MP20046
Fast Transient Response, 2A
Low Dropout Voltage Regulator
DESCRIPTION
The MP20046 is a low dropout linear regulator
supplying up to 2A current with 210mV dropout
voltage. The output voltage is preset internally
which ranges from 1.5V to 3.3V.
An internal PMOS pass element is used to
allow a low 75µA ground current at full load and
drops down to 1uA when the device is disabled,
making the MP20046 suitable for battery-power
devices. Integrated power good (PG) function
resets microcomputer and microprocessor
systems in the event of an under voltage
condition. MP20046 are designed to have fast
response for larger load and line transient
response. Other features include current limit
and thermal protection.
The MP20046 is available in thermally
enhanced SOIC8 package and 10-pin QFN
package.
