Datasheet - Detailed Description
8 Detailed Description
Regulator On/Off Operation
The AS13986 outputs (V
OUT1
and V
OUT2
) are enabled by pulling the corresponding EN
x
pin high (1.4V) and disabled
by pulling the EN
x
pin low (0V). For reliable operation, the signal source used to drive the EN
x
input must be capable
of swinging above and below the specified turn-on/off voltage thresholds listed in
Table 3 on page 4
(Enable Input
Logic Low and Enable Input Logic High parameters).
Note:
Reliable enable/disable operation of V
OUT1
and V
OUT2
is guaranteed by driving the EN
x
pins with t
R
and t
F
=
10ms.
Fast Turn-On Time
In normal operation, the AS13986 outputs are turned on when V
REF
reaches its regulated value (1.23V nominal). Turn-
on time is decreased by charging the capacitor at pin BYPASS with the internal 70μA current source. The current
source is turned off when the bandgap voltage reaches approximately 95% of its regulated value.
Turn-on time is determined by the time constant of the bypass capacitor; smaller capacitor values decrease turn-on
time, although noise reduction decreases as well. Therefore, turn-on time and noise reduction must be taken into con-
sideration when choosing the value of the bypass capacitor.
