FP6146
300mA Low Noise High PSRR
LDO with Shutdown
Description
Features
The FP6146 is a low dropout, low noise, high PSRR,
very low quiescent current positive linear regulator.
The FP6146 can supply 200mA output current with
low dropout voltage at about 300mV that optimized
for battery-powered systems or portable wireless
devices such as mobile phones. The shutdown
function can provide remote control for the external
signal to decide the on/off state of FP6146 that
consumes less than 0.1µA during shutdown mode.
Low Dropout Voltage of 300mV at 200mA
Low 30μVrms Output Noise
Guaranteed 300mA Output Current
High Power Supply Rejection Ratio of 70dB at
10kHz
Very Low Quiescent Current at 35µA
Max. 2% Output Voltage Accuracy
Needs Only 1µF Capacitor for Stability
Fast Response in Line/Load Transient
Thermal Shutdown Protection
Current Limit Protection
Low-ESR Ceramic Capacitor for Output Stability
Miniature Packages:
SOT-23-3, SOT-23-5, TSOT-23-5, TDFN-6
(1.6mm×1.6mm), SC-82-4 and SC-70-5
RoHS Compliant
The FP6146 regulator is able to operate with output
capacitors as small as 1µF for stability. Other than
the current limit protection, FP6146 also offers the on
chip thermal shutdown feature providing protection
against overload or any condition when the ambient
temperature exceeds the maximum junction
temperature.
The FP6146 offers high precision output voltage of

Functional Pin Description
Pin Name
Pin Function
Power is supplied to this device from this pin which is required an input filter capacitor. In general, the input
capacitor in the range of 1µF to 10µF is sufficient.
VIN
The output supplies power to loads. The output capacitor is required to prevent output voltage from oscillation.
The FP6146 is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for
application with larger load transients. The large output capacitor could reduce output noise, improve stability
and PSRR.

Application Information
2. Protection Features
The FP6146 is a low dropout linear regulator that
could provide 200mA output current at dropout
voltage about 300mV. Current limit and on chip
thermal shutdown features provide protection
against any combination of overload or ambient
temperature that could exceed maximum junction
temperature.
In order to prevent overloading or thermal condition
from damaging the device, FP6146 has internal
thermal and current limiting functions designed to
protect the device. It will rapidly shut off PMOS
pass element during over-temperature condition.
3. Thermal Consideration
1. Output and Input Capacitor
The power handling capability of the device will be
limited by allowable operation junction temperature
(125ºC). The power dissipated by the device will
be estimated by PD=IOUT(VIN-VOUT). The power
dissipation should be lower than the maximum
powerꢃ dissipationꢃ listedꢃ inꢃ “Absoluteꢃ Maximumꢃ
Ratings”ꢃsection.
The FP6146 regulator is designed to be stable with a
wide range of output capacitors. The ESR of the
output capacitor affects stability. Larger value of the
output capacitor decreases the peak deviations and
improves transient response for larger current
changes.
The capacitor types (aluminum, ceramic, and
tantalum) have different characterizations such as
temperature and voltage coefficients. All ceramic
capacitors are manufactured with a variety of
dielectrics, each with different behavior across
temperature and applications. Common dielectrics
used are X5R, X7R and Y5V. It is recommended to
use 1µF to 10µF X5R or X7R dielectric ceramic
capacitors with 30m to 50m ESR range between
4. Shutdown Operation
The FP6146 is shutdown by pulling the ꢀꢁꢂ
input low, and turned on by driving the ꢀꢁꢂ high.
If ꢀꢁꢂ pin floating, the FP6146 will shut down
because ꢀꢁꢂ pin has built-in a pull low resistor
(refer to Block Diagram).
device outputs and ground for stability.
The
FP6146 is designed to be stable with low ESR
ceramic capacitors and higher values of capacitors
and ESR could improve output stability. The ESR of
output capacitor is very important because it
generates a zero to provide phase lead for loop
stability.
There are no requirements for the ESR on the input
capacitor, but its voltage and temperature coefficient
have to be considered for device application
environment.
