Exceeding the absolute maximum ratings may damage the device.
The device is not guaranteed to function outside its operating ratings.
The maximum allowable power dissipation of any T
(ambient temperature) is P
= (T
–
T
)/
θ
JA
. Exceeding the maximum allowable power
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The
θ
JA
of the MIC5253-x.xBC5 (all versions) is
400
°
C/W on a PC board (see

section for further details).
Devices are ESD sensitive. Handling precautions recommended.
Specification for packaged product only.
Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from
0.1mA to 100mA. Changes in output voltage due to 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.
For outputs below 2.7V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.7V. Minimum input operating voltage
is 2.7V.
Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin current.
