General Description
The MIC5200 is an efficient linear voltage regulator
with very low dropout voltage (typically 17 mV at light
loads and 200 mV at 100 mA), and very low ground
current (1 mA at 100 mA output), offering better than
1% initial accuracy with a logic-compatible ON/OFF
switching input. Designed especially for hand-held
battery-powered devices, the MIC5200 is switched by
a CMOS- or TTL-compatible logic signal. The ENABLE
control may be tied directly to V
IN
if unneeded. When
disabled, power consumption drops nearly to zero. The
ground current of the MIC5200 increases only slightly
in dropout, further prolonging battery life. Key MIC5200
features include protection against reversed battery,
current limiting, and overtemperature shutdown.
The MIC5200 is available in several fixed voltages and
accuracy configurations. Other options are available;
contact Microchip for details.

2:
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
3:
Regulation is measured at 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 due to
heating effects are covered by the thermal regulation specification.
4:
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.
5:
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.
6:
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

Note 2
Note 1:
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.
2:
The maximum allowable power dissipation at any ambient temperature is calculated using: P
(MAX)
=
(T
J(MAX)
– T
A
) ÷ θ
JA
. Exceeding the maximum allowable power dissipation will result in excessive die tem-
perature, and the regulator will go into thermal shutdown. The θ
JC
of the MIC5200-x.xYS is 15°C/W and
θ
JA
for the MIC5200YM is 160°C/W mounted on a PC board (see
Thermal Considerations
for further
details).
