Low Dropout CMOS Voltage Regulators
LM1114
Features
Applications
● Maximum
output current 250mA
● Highly accurate : output voltage+/-2%
● Low power consumption : typ. 2μA
● Small input/output differential:
0.4V at 160mA(Vout=2.5V, 3.0V, 3.3V, 3.6V)
0.12V at 100mA(Vout=5V)
●Battery
powered equipment
●Palmtops
●Portable cameras and video recorders
●Reference voltage sources
Product Description
The LM1114 series is a group of positive voltage output, three-pin regulators, that provide a
high current even when the input/output voltage differential is small. Low power consumption
and high accuracy is achieved through CMOS and programmable fuse technologies. Output
voltage: 2V to 6V in 0.1V increments.
The LM1114 consists of a high-precision voltage reference, an error correction circuit, and a
current limited output driver. Transient response to load variations is improved in comparison
to the existing ones.
