Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see
the Electrical Characteristics tables.
Note 2:
To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3:
Limits appearing in
boldface
type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for
T
A
= T
J
= 25°C.
Note 4:
The maximum allowable power dissipation is a function of the maximum junction temperature T
J
(MAX), the junction-to ambient thermal resistance
θ
J-A
and
the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using:
P(MAX)
=
T
J
(MAX) - T
A
θ
J - A
Where the value of the junction-to-ambient thermal resistance are as follows: 195°C/W for the TO-92 (N) package, 110°C/W for SOT-89 (L), 220°C/W for 5 lead
SOT-23 (M1) and 160°C/W for the molded plastic SO-8 (S).
Note 5:
Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential.
