FP6141  
100mA Ultra-Low Quiescent Current  
Low Dropout Regulator  
Description  
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  
● Current Limit Protection  
● Thermal Shutdown Protection  
● 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.  
● RoHS Compliant  
The FP6141 is available in space saving SOT-23-3,  
SOT-23-5 and TDFN-6 packages.  
Applications  
● Battery-Powered Equipment  
● Notebook Computer  
● Hand-Held Instrument

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.
