FAN1537
Application Hints
External Capacitors
Like any low-dropout regulator, the FAN1537 requires
external capacitors for stability.
Input Capacitor
A Tantalum input capacitor of 22µF is recommended. This
capacitor must be located at a distance of no more than 0.5"
from the input pin of the device and returned to a clean ana-
log ground.
Output Capacitor
The FAN1537 is designed to work with Ceramic or Tantalum
load capacitors.
A value of 22µF is recommended on each output, but the
value can be reduced to 10µF to save space.
Additional capacitance can be added without limit for better
performance, e.g. improved transient response and lower
noise.
When a Ceramic multilayer capacitor is used, the X7R
dielectric is recommended which holds the capacitance
within ±15%. The output capacitor should be located not
more than 0.5" from the output pins of the device and
returned to a clean analog ground.
