Application Information
The FP6160 is a high voltage, low dropout linear
regulator that could provide 150mA output current at
800mV dropout voltage. Besides, current limit and
on chip thermal shutdown features provide protection
against any combination of overload or ambient
temperature that could exceed junction temperature.
ESR could improve output stability. So the ESR
of output capacitor is very important because it
generates a zero to provide phase lead for loop
stability. It is recommended to use 1µF to 10µF
X5R or X7R dielectric ceramic capacitors with
ꢑ0mΩꢃtoꢃꢒ0mΩꢃE Rꢃrangeꢃbetweenꢃꢄꢅꢉꢊꢃandꢃ
GND for transient stability.
Shutdown Control
Larger value of the output capacitor decreases
the peak deviations and improves transition
response for larger current changes.
Force ꢀꢁꢂ pin high to enable the FP6160 and
turned off the device by pulling it low. The ꢀꢁꢂ
pinꢃcan’tꢃbeꢃleft floating and must be tied to the VIN if
not used.
The ESR is not essential for input capacitor, but
its voltage and temperature coefficient have to be
considered for device application environment.
Output Voltage Setting
Over Temperature Protection
The output voltage of regulator is determined by
connecting external resistor dividers. The external
resistor divider connects with FB pin. The output
voltage is determined by the following equation:
Over temperature protection function is
integrated in the chip. The thermal protection
function prevents the excessive power dissipation
form overheating. When the chip temperature is
higher than 150C, the controller will be
shutdown. When the junction temperature cools
down to a constant value, the thermal protection
will be released and the chip will operate normally
again.

PSRR (Power Supply Rejection Ratio)
The FP6160 has high 65dB PSRR. Ripple rejection
is the ability of the regulator to reduce input voltage
ripple. It is specified with a 120Hz and 1VP-P signal
Thermal Consideration
applying to input with a 1µF output capacitor. Ripple
rejection, expressed in dB, is the ratio of output ripple
to input ripple.
The power handling capability of the device will
be limited by allowable operation junction
temperature (125C). The power dissipated by
the device will be estimated by PD = IOUT
Output and Input Capacitor
(VIN-VOUT). The power dissipation should be
lower than the maximum power dissipation listed
inꢃ“AbsoluteꢃMaximumꢃRatings”ꢃsection.
The FP6160 is designed to be stable with low ESR
ceramic capacitors. Higher values of capacitors and
