P1-P3P4-P6P7-P8
August 2004 1 MIC5213
MIC5213 Micrel
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, 2.6V, 2.7V, 2.8V, 3.0V,
3.3V, 3.6V, and 5.0V fixed voltages. Other voltages are
available; contact Micrel for details.

Note 1. Exceeding the absolute maximum rating may damage the device.
Note 2. The device is not guaranteed to function outside its operating rating.
Note 3. Devices are ESD sensitive. Handling precautions recommended.
Note 4. 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 power dissipation at any ambient temperature is calculated using:
P
D(max)
= (T
J(max)
– T
A
)
÷ θ
JA
. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator
will go into thermal shutdown. θ
JA
of the SC-70-5 is 450°C/W, mounted on a PC board.
Note 5. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 6. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects
are covered by the thermal regulation specification.
Note 7. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V
differential.
Note 8. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of
the load current plus the ground pin current.
Note 9. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line
regulation effects. Specifications are for an 80mA load pulse at V
IN
= 16V for t = 10ms.
