Features
Low Power Consumption: typ 2.0A at V
OUT
= 5V
All-CMOS design in SOT-23 and SOT-89 packages gives
optimal size and power performances.
Highly accurate output 2% (1%)
Maximum output current: 250mA (Limited to 150mW
power dissipation SOT-23, 500mW SOT-89)
Output Voltage Range: 2.0V to 6.0V
Applications
Battery-powered Equipment
Reference voltage sources
Palmtops
Portable cameras and video recorders
Description
250mA CMOS LDO in a SOT-23 package, featuring 120mV
of dropout voltage at 100mA and 380mV at 200mA current
levels.
The part offers 2% accuracy on outputs, yet draws only 2A
of current. Short-circuit protection is standard.
The part comes in both 3-lead SOT-23 (150mW) and 3-lead
SOT-89 (500mW) to handle a variety of voltage and current
levels.
Transient response to load variations have improved in
comparison to the existing series.
Low Power consumption and high accuracy is achieved
through CMOS and laser trimming technologies.
