ILC7362
Final
SOT-23 CMOS Negative LDO
www.fairchildsemi.com
General Description
100mA negative LDO in SOT-23 package.
This CMOS device regulates a negative supply down to a
fixed voltage level at ±2% accuracy.
It offers exceptional LDO performance of 120mV dropout at
50mA current levels.
The device also comes in a 3-lead SOT-89 package, for a
number of voltage and current offerings.
Features
• All-CMOS design in SOT-23 and SOT-89 packages
gives optimal size and power performance
• ±2% precistion outputs
• 3µA of Iq
• Package and Voltage options alow:
100mA-5V Regulator
