*Capacitance value shown is minimum required to assure stability, but may be increased without limit. Larger output capacitor provides improved dynamic
response.
**Shutdown must be actively terminated (see Application Hints). Tie to INPUT (pin 4) if not used.
Application Hints
LLP Package Devices
The LP2987/LP2988 is offered in the 8 lead LLP surface
mount package to allow for increased power dissipation
compared to the SO-8 and Mini SO-8. For details on thermal
performance as well as mounting and soldering specifica-
tions, refer to Application Note AN-1187.
EXTERNAL CAPACITORS
As with any low-dropout regulator, external capacitors are
required to assure stability. These capacitors must be cor-
rectly selected for proper performance.
INPUT CAPACITOR: An input capacitor (
≥ 2.2 F) is re-
quired between the LP2987/8 input and ground (amount of
capacitance may be increased without limit).
This capacitor must be located a distance of not more than
0.5” from the input pin and returned to a clean analog
ground. Any good quality ceramic or tantalum may be used
for this capacitor.
OUTPUT CAPACITOR: The output capacitor must meet the
requirement for minimum amount of capacitance and also
have an appropriate E.S.R. (equivalent series resistance)
value.
Curves are provided which show the allowable ESR range
as a function of load current for 3V and 5V outputs.
