ILC7070
SOT-23 CMOS LDO Regulator with Shutdown
General Description
Features
150mA CMOS LDO regulator in a 5-lead SOT-23 package,
featuring 120mV dropout at 100mA levels and nearly negli-
gible dropout below 5mA.
The part offers ±2% precision as standard, yet draws only
5µA of current in operation and drops to 0.5µA in shutdown.
The outputs offer short-circuit protection, and the shutdown
pin has an internal pull-down which will disable the output if
the pin is left floating.
• All-CMOS design in 5-lead SOT-23 package
• ±2% precision outputs
• Up to 150mA output current
• 120mV dropout at 100mA load
• Only 5µA quiescent current at full load
• 0.5µA quiescent current in shutdown
• Voltage options allow:
50mA 5V Regulator
50mA 5V to 3.3, 3.0, or 2.5V Convertor
150mA 3.3V or 3.0V to 2.5V Convertor
Applications
• Battery-powered Equipment
• Reference voltage sources
• Portable Cameras and Video Recorders
• PDAs
