Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation is a function of the maximum junction temperature, T
, the junction-to-ambient thermal
resistance,
θ
JA
, and the ambient temperature, T
. The maximum allowable power dissipation at any ambient temperature is calculated using:
P
= (T
– T
)
θ
. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will
go into thermal shutdown. The
θ
of the MIC5204BS is 15
°
C/W and
θ
JA
for the MIC5204BM is 160
°
C/W mounted on a PC board (see
“Thermal Considerations” for details).
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
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.
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 dissipation is applied, excluding load or line
regulation effects. Specifications are for a 500mA load pulse at V
IN
= 6V for t = 10ms.
