Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2:
The maximum power dissipation is a function of T
,
θ
, and T
. The maximum allowable power dissipation at any ambient temperature is
P

. All numbers apply for packages soldered directly into a PC board.
Note 3:
For testing purposes, ESD was applied using human body model, 1.5k
in series with 100pF.
Note 4:
Typical Values represent the most likely parametric norm.
Note 5:
All limits are guaranteed by testing or statistical analysis.
Note 6:
Load and line regulation are measured at constant junction room temperature.
Note 7:
The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input voltage. It is measured when the
output voltage has dropped 100mV from the nominal value obtained at V
IN
= V
OUT
+1.5V.
Note 8:
The minimum output current required to maintain regulation.
Note 9:
Minimum pad size of 0.038in
