Features
The FP6141 is a CMOS low dropout voltage (LDO)
regulator with ultra-low quiescent current of 4µA,
designed for battery-operated applications. Wide
range of output voltages can be used, ranging from
1.2V to 3.3V.
● Ultra-Low Quiescent Current at 4µA
● High Output Voltage Accuracy at ±2%
● Low Dropout Voltage of 250mV at 100mA
● Operating Voltage Range from 2V to 5.5V

● 1µF Output Capacitor Required for Stability
● Chip Enable Control (FP6141XXS5 and
FP6141XXWD only)
Other features include current limit protection,
thermal shutdown protection and high output voltage
accuracy. The requirement of only 1µF input and
output capacitor makes it ideal in space-sensitive
applications.

Application Information
The FP6141 is suitable for power saving battery
application with ultra-low 4µA quiescent current.
Current limit and on chip thermal shutdown features
provide protection against any combination of
overload or ambient temperature that could exceed
maximum junction temperature.
Capacitor Selection
The ceramic capacitor is ideal for FP6141
application. 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.
Shutdown Control
The capacitor types (ceramic, aluminum and
tantalum) have different characterizations such as
voltage and temperature coefficients. All ceramic
capacitors are manufactured with a variety of
dielectrics, each with different behavior across
Force Eꢀ pin low to enable the FP6141 and turn off
the device by pulling it high. The Eꢀ pin can’t be left
floating and must be tied to the ground if not used.
Thermal Shutdown
temperature
and
applications.
Common
Thermal shutdown is employed to prevent the device
damaged from the junction temperature exceeding
safe margins mainly due to short circuit or current
limit. Moreover, the device will return to normal
operation when the junction temperature is down to a
dielectrics used are X5R, X7R and Y5V. It is
recommended to use 1µF to 10µF X5R or X7R
dielectric ceramic capacitors, because X5R or X7R
hold their capacitance over wider voltage and
temperature ranges than other Y5V or Z5U types.
The ESR of output capacitor is very important,
because it generates a zero to provide phase lead
for loop stability. The input capacitor can reduced
peak current and noise at power source.
constant temperature.
Though temperature
protection circuit is built in to protect IC, the
maximum power dissipation design within Tj (max) is
needed. The thermal protection is independent to
each channel.
Thermal Consideration
The power handling capability of the device will be
limited by maximum 125C operation junction
temperature. The power dissipated by the device
will be estimated by PD = IOUT (VIN-VOUT). The
power dissipation should be lower than the maximum
power dissipation listed in “Absolute Maximum
Ratings” section.
