Product Summary

The LT1184FIS#TR is a switching regulator.The LT1184FIS#TR operates with input; (2)supply voltages from 3V to 30V. The ICs also have a battery supply voltage pin that operates from 4.5V to 30V. The LT1182/LT1183 draw 9mA typical quiescent current while the LT1184FIS#TR draws 6mA typical quiescent current. An active low shutdown pin typically reduces total supply current to 35mA for standby operation. A 200kHz switching frequency minimizes the size of required magnetic components. The use of current mode switching techniques with cycle by cycle limiting gives high reliability and simple loop frequency compensation. The LT1184FIS#TR is all available in 16 pin narrow SO packages. The LT1184FIS#TR applications are: (1)Notebook and Palmtop Computers; (2)Portable Instruments; (3)Automotive Displays; (4)Retail Terminals.
