ILC7070
SOT-23 CMOS LDO Regulator with Shutdown
Features
* * * * * * * All-CMOS design in 5-lead SOT-23 package 2% precision outputs Up to 150mA output current 120mV dropout at 100mA load Only 5A quiescent current at full load 0.5A quiescent current in shutdown Voltage options allow: 50mA 5V Regulator 50mA 5V to 3.3, 3.0, or 2.5V Converter 150mA 3.3V or 3.0V to 2.5V Converter
Description
150mA CMOS LDO regulator in a 5-lead SOT-23 package, featuring 120mV dropout at 100mA levels and nearly negligible dropout below 5mA. The part offers 2% precision as standard, yet draws only 5A of current in operation and drops to 0.5A 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.
Applications
* * * * Battery-powered Equipment Reference voltage sources Portable Cameras and Video Recorders PDAs

VOUT = 2.5V, TA =25C Parameter Output Voltage Maximum Output Current Load Stability Input/Output Voltage Differential Supply Current 1 Supply Current 2 Input Stability Input Voltage Output Voltage Temperature Characteristics CE Input Current CE ON Voltage CE OFF Voltage Notes: 1. VOUT means the output voltage when "VOUT + 1.0V" is provided at the VIN pin while maintaining a certain IOUT value. 2. VIN1 is defined as the input value that is gradually decreased until the output value reaches VOUT x 98%. 3. Vdif is defined as "VIN1-VOUT." 4. IOUT: this is limited by continuous total power dissipation in the package. 5. When VCE is LOW or OPEN, the output is disabled. Note: CE pin is a CMOS input. Because of this, when the input voltage reaches VIN/2, a rush current will start to flow.
