New Japan Radio Co.,Ltd. www.njr.com NJM2352 LOW POWER SWITCHING REGULATOR GENERAL DESCRIPTION PACKAGE OUTLINE 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 NJM2352D NJM2352M 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 280A. The NJM2352 can be used as a building block in three basic applications : step-up, step-down and inverting.
