DESCRIPTIO

AXI U
RATI GS
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鈥檚 in-
house Class S flow to yield circuits usable in stringent
military applications.
