MIC5208
Dual 50mA LDO Voltage Regulator
Preliminary Information
General Description
The MIC5208 is a dual linear voltage regulator with very low
dropout voltage (typically 20mV at light loads and 250mV at
50mA), very low ground current (225
μ
A at 10mA output), and
better than 3% initial accuracy. It also features individual
logic-compatible enable/shutdown control inputs.
Designed especially for hand-held battery powered devices,
the MIC5208 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 con-
sumption drops nearly to zero. Dropout ground current is
minimized to prolong battery life.
Key features include current limiting, overtemperature shut-
down, and protection against reversed battery.
The MIC5208 is available in 3.0V, 3.3V, 3.6V, 4.0V and 5.0V
fixed voltage configurations. Other voltages are available;
contact Micrel for details.
