The MIC5202 is a dual linear voltage regulator with low
dropout voltage (typically 17 mV at light loads and
210 mV at 100 mA), and low ground current (1 mA at
100 mA per output). Ideal for battery-operated
applications, the MIC5202 offers 1% output voltage
accuracy and dual enable pins. The enable pins may
be driven individually or tied directly to V
IN
. When the
part is disabled, power consumption drops to nearly
zero. The MIC5202 ground current increases slightly in
dropout, which minimizes power consumption and
increases battery life. Some key features include
reversed battery protection, current-limit, and
overtemperature protection.
The MIC5202 is available in fixed output voltages in the
small 8-pin SOIC package.

Specification for packaged product only.
Output voltage temperature coefficient is defined as the worst case voltage change divided by the tem-
perature range.
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Parts
are tested for load regulation in the load range from 0.1 mA to 100 mA. Changes in output voltage caused
by heating effects are covered by the thermal regulation specification.
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.
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.
Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipa-
tion is applied, excluding load or line regulation effects. Specifications are for a 100 mA load pulse at
V
IN
= 26V for t = 10 ms.

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., T
A
, T
J
,
JA
). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
