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
● DSC
