Electrical Characteristics
(Continued)
Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the
device outside of its rated operating conditions.
Note 2:
The ESD rating of pin 3 is 1 kV.
Note 3:
The maximum allowable power dissipation is a function of the maximum junction temperature, T
(MAX), the junction-to-ambient thermal resistance,
θ
J-A
,
and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperture is calculated using:
Where the value of
θ
for the SOT-23 package is 240C/W in a typical PC board mounting. Exceeding the maximum allowable dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown.
Note 4:
If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2983 output must be diode-clamped to ground.
Note 5:
The output PNP structure contains a diode between the V
to V
terminals that is normally reverse-biased. Reversing the polarity from V
IN
to V
OUT
will
turn on this diode and possibly cause a destructive latch-up condition (see Application Hints).
Note 6:
Limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 7:
The ON/OFF input must be properly driven to prevent possible misoperation. For details, refer to Application Hints.
Note 8:
The LP2983 has foldback current limiting which allows a high peak current when V
OUT
>
0.5V, and then reduces the maximum output current as V
OUT
is
forced down to ground (see Typical Performance Characteristics curves).
