Parameters identified with
boldface type
apply over the full operating temperature range.
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. For guaranteed specifications and test conditions, see the
Electrical Characteristics
.
The guaranteed specifications apply only for the test conditions listed.
Note 2:
Line and Load regulation are guaranteed up to the maximum power dissipation of 1.2 W. Power dissipation is determined by the input/output differential
and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
Note 3:
See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction
temperature by low duty cycle pulse testing. Load regulation is measured at the output lead ~1/8” from the package.
Note 4:
Dropout voltage is specified over the full output current range of the device.
Note 5:
Minimum load current is defined as the minimum output current required
to maintain regulation. When 1.5V
≤
(V
IN
- V
OUT
)
≤
12V the device is
guaranteed to regulate if the output current is greater than 10mA.
