_______________________________________________________________________________________
(PSRR) is therefore not specified. Since the output must
be connected to a 10F or larger filter capacitor, the
capacitor characteristics dominate the PSRR. Large
values of input and output capacitors reduce the ripple.
In addition, both DD and LBI/LBO can trigger on the
lowest DC component of the ripple, particularly at high
load currents. In the case of the low-battery detector,
the ripple can be effectively filtered out by placing a
capacitor to ground in parallel with the LBI input pin.
The high resistance values that can be used for the
voltage divider allow relatively small capacitance val-
ues to form an effective lowpass filter at 120Hz. When
power is first applied, however, this filter tends to hold
LBO low longer than normal.
Transient Considerations
The low operating current and gain-bandwidth product
of the internal reference and amplifier result in limited
rejection of fast-step input changes. Negative-going
steps, which occur in under 100s, may turn off the out-
put for several milliseconds. An input filter (nominally
10F) is recommended if input changes greater than
1V and faster than 100s (other than turn-on or turn-off)
are anticipated. Figure 12 shows the output response to
a 10mA/100mA instantaneous load step. The relation-
ship between output-capacitor ESR and load-transient
response is explained in the Output Capacitor section.
