ILC7062
SOT-23 CMOS LDO
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
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.
Applications
* * * * Battery-powered Equipment Reference voltage sources Palmtops Portable cameras and video recorders
