Product Summary
The LT1614CS8 is a fixed frequency, inverting mode switching reglator that operates from an input voltage as low as 1V. Utilizing a low noise topology, the LT1614CS8 can generate a negative output down to -24V from a 1V to 5V input. Fixed frequency switching ensures a clean output free from low frequency noise. The LT1614CS8 contains a lowbattery detector with a 200mV reference and shuts down to less than 10mA. No load quiescent current of the LT1614CS8 is 1mA and the internal NPN power switch handles a 500mA current with a voltage drop of just 295mV. High frequency switching enables the use of small inductors and capacitors. Ceramic capacitors can be used in many applications, eliminating the need for bulky tantalum types. The LT1614CS8 is available in 8-lead MSOP or SO packages.
