ILC7062
SOT-23 CMOS LDO
General Description
250mA CMOS LDO in a SOT-23 package, featuring
120mV of dropout voltage at 100mA current levels
and near-zero dropout below 5mA.
The part offers ±2% accuracy on outputs, yet draws
only 2µA of current. Short-circuit protection is stan-
dard.
The part comes in both 3-lead SOT-23 and 3-lead
SOT-89 to handle a variety of voltage and current
levels.
Features
u
All-CMOS design in SOT-23 and SOT-89 packages
gives optimal size and power performance
u
