MIC5213
Teeny™ SC-70 µCap Low-Dropout Regulator
Advance Information
General Description
The MIC5213 is a µCap 80mA linear voltage regulator in the
Teeny™ SC-70 package. Featuring half the footprint of the
standard SOT-23 package, this Teeny SC-70 regulator has
very low dropout voltage (typically 20mV at light loads and
300mV at 80mA) and very low ground current (225µA at
20mA output). It also offers better than 3% initial accuracy
and includes a logic-compatible enable input.
The µCap regulator design is optimized to work with low-
value, low-cost ceramic capacitors. The outputs typically
require only 0.47µF of output capacitance for stability.
Designed especially for hand-held, battery-powered devices,
the MIC5213 can be controlled by a CMOS or TTL compatible
logic signal. When disabled, power consumption drops nearly
to zero. If on-off control is not required, the enable pin may be
tied to the input for 3-terminal operation. The ground current
of the MIC5213 increases only slightly in dropout, further
prolonging battery life. Key MIC5213 features include current
limiting, overtemperature shutdown, and protection against
reversed battery.
The MIC5213 is available in 2.5V, 2.8V, 3.0V, 3.3V, and 3.6V
fixed voltages. Other voltages are available; contact Micrel
for details.
