ILC7062
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 ±2% precision outputs
u 2µA of Iq at 5Vout
u Package and Voltage options allow:
100mA 5V Regulator
50 & 250mA 5V to 3.3 or 3.0V converter
50 & 150mA 5V to 2.5V converter
150mA 3.3 or 3.0V to 2.5V converter
Applications
u Battery-powered Equipment
u Reference voltage sources
u Portable Cameras and Video Recorders
u Power Failure Detection
u PDAs

Notes:
1. VOUT means the output voltage when “VOUT+1.0V” is provided at the VIN pin while maintaining a certain IOUT value.
2. Vdif is defined as “VIN-VOUT” where VOUT = VSET X 0.98.
3. IOUTmax. = This is specified for SOT-89 package. For SOT-23, it is limited by continuous total power dissipation.
