Typical Application

RH1009 Typical Application

Description

The RH1009 is a general purpose 2.5V shunt regulator diode designed to operate over a wide current range while maintaining good stability with time and temperature. The adjust terminal allows either temperature coefficient to be minimized or the reference voltage to be adjusted without changing the temperature coefficient. Because it operates as a shunt regulator it can be used equally well as a positive or negative reference.

The wafer lots are processed to Linear Technology’s in-house Class S flow to yield circuits usable in stringent military applications.
