Notes:
3. Exceeding the absolute maximum ratings may damage the device.
4. The device is not guaranteed to function outside its operating ratings.
5. The maximum allowable power dissipation is a function of the maximum junction temperature, T
J(max)
the junction-to-ambient thermal resistance,
θ
JA
,
and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated using: P
D(max)
= (T
J(max)
– T
A
)
÷
θ
JA
, where
θ
JA
is 235°C/W. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go
into thermal shutdown. See the “Thermal
Considerations”
sub-section in the
Application Information
for details.
6. Devices are ESD sensitive. Handling precautions are recommended.
7. Specification for packaged product only.
8.
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
9. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range
from 100µA to 100mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
10. 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.
11.
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
