General Description
The MIC69153 is the 1.5A output current member of
the MIC69xxx family of high current, low voltage
regulators, that support currents of 1A, 1.5A, 3A, and
5A. The MIC69153 operates from a single low voltage
supply, yet offers high precision and ultra-low dropout
of 500 mV under worst case conditions.
The MIC69153 operates from an input voltage of 1.65V
to 5.5V. It is designed to drive digital circuits requiring
low voltage at high currents (i.e. PLDs, DSP,
microcontroller, etc.). These regulators are available
only in adjustable output voltage option and can
support output voltages down to 0.5V.
The µCap design of the MIC69153 is optimized for
stability with low value low ESR ceramic output
capacitors.
Features of the MIC69153 include thermal shutdown
and current-limit protection. Logic enable and error flag
pins are also available.
The MIC69153 is offered in a tiny 10-pin 3 mm x 3 mm
DFN package and an ePAD SOIC-8 package. Both
packages have an operating temperature range of
–40°C to +125°C.

† Notice:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability. Specifications are for packaged product only.
‡ Notice:
The device is not guaranteed to function outside its operating ratings.

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. For outputs below 1.65V, dropout voltage is considered the
input-to-output voltage differential with the minimum input voltage of 1.65V. Minimum input operating
voltage is 1.65V.

Conditions
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.
