NJM2352
LOW POWER SWITCHING REGULATOR
■ GENERAL DESCRIPTION
The NJM2352 is the industry's first monolithic low power switching
regulators available in an 8-lead mini-DIP, and designed specifically
for battery operated instruments. They each contain a 1.3V
temperature compensated bandgap reference, adjustable free
running oscillator, voltage comparator, low battery detection circuitry,
and a 200mA switch transistor with all of the functions required to
make a complete low power switching regulator.
These regulators can achieve up to 80% efficiency in most
applications while being able to operate over a wide input supply
voltage range, 2.6V to 24V at a very low quiescent drain of 280µA.
The NJM2352 can be used as a building block in three basic
applications : step-up, step-down and inverting.
