Electrical Characteristics
(Continued)
Note 12:
The shutdown input equivalent circuit is the base of a grounded-emitter NPN transistor in series with a current-limiting resistor. Pulling the shutdown input
high turns off the main regulator. For more details, see Application Hints.
Note 13:
The auxiliary regulator output has foldback limiting, which means the output current reduces with output voltage. The tested limit is for V
OUT
= 0V, so the
output current will be higher at higher output voltages.
Note 14:
This test is performed with the auxiliary comparator output sinking 400 μA of current. At the upper trip point, the comparator output must be
≥
2.4V. At the
low trip point, the comparator output must be
≤
0.4V.
Note 15:
Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current, output load current, and
current through the external resistive dividers (if used).
Note 16:
All pins are rated for 2 kV, except for the auxiliary feedback pin which is rated for 1.2 kV (human body model, 100 pF discharged through 1.5 k
).
Typical Performance Characteristics
Unless otherwise specified: V
IN
= 6V, C
L
= 2.2 μF (Main Out-
put) and 10 μF (Auxiliary Output), Feedback is tied to 5V Tap pin, C
= 1 μF, V
= 0V, Main Output pin is tied to Output
Sense pin, Auxiliary Output is programmed for 5V. The main regulator output has a 1 mA load, the auxiliary output has a
