MIC5210-MPYMM

Manufacturer Part Number
MIC5210-MPYMM
Description
Dual 150mA LDO Regulator
Manufacturer
MICREL [Micrel Semiconductor]
Datasheet
General Description
The MIC5210 is a dual linear voltage regulator with very
low dropout voltage (typically 10mV at light loads and
140mV at 100mA), very low ground current (225µA at
10mA output), and better than 1% initial accuracy. It also
features
control inputs.
Both regulator outputs can supply up to 150mA at the
same time as long as each regulator’s maximum junction
temperature is not exceeded.
Key features include an undervoltage monitor with an error
flag output, a reference bypass pin to improve its already
low-noise performance (8-pin versions only), reversed-
battery protection, current limiting, and overtemperature
shutdown.
Designed especially for hand-held battery powered
devices, the MIC5210 can be switched by a CMOS or TTL
compatible logic signal, or the enable pin can be
connected to the supply input for 3-terminal operation.
When disabled, power consumption drops nearly to zero.
Dropout ground current is minimized to prolong battery life.
Key features include current limiting, overtemperature
shutdown, and protection against reversed battery.
The MIC5210 is available in 2.7V, 2.8V, 3.0V, 3.3V, 3.6V,
4.0V and 5.0V fixed voltage configurations. Other voltages
are available; contact Micrel for details.
