Notes:
1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specications do not apply when operating
the device outside of its operating ratings. 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
. Exceeding the maximum allowable power dissipation will result in excessive die
temperature, and the regulator will go into thermal shutdown. See Table 1 and the “Thermal Considerations” section for details.
2. The device is not guaranteed to function outside its operating rating.
3. Specication for packaged product only.
4. Output voltage temperature coefcient is dened as the worst case voltage change divided by the total temperature range.
5. 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 500mA. Changes in output voltage due to heating effects are covered by the thermal regulation specication.
6. Dropout voltage is dened as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differen-
tial.
7. 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.
8. V
EN
is the voltage externally applied to devices with the EN (enable) input pin.
9. Thermal regulation is dened as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regu-
lation effects. Specications are for a 500mA load pulse at V
IN
= 12V for t = 10ms.
10. C
BYP
is an optional, external bypass capacitor connected to devices with a BYP (bypass) or ADJ (adjust) pin.
