The LT

1021 is a precision reference with ultralow drift

and noise, extremely good long term stability and almost

total immunity to input voltage variations. The reference

output will both source and sink up to 10mA. Three

voltages are available: 5V, 7V and 10V. The 7V and 10V

units can be used as shunt regulators (two-terminal zeners)

with the same precision characteristics as the three-

terminal connection. Special care has been taken to mini-

mize thermal regulation effects and temperature

induced hysteresis.

The LT1021 references are based on a buried zener diode

structure that eliminates noise and stability problems

associated with surface breakdown devices. Further, a

subsurface zener exhibits better temperature drift and

time stability than even the best bandgap references.

Unique circuit design makes the LT1021 the first IC

reference to offer ultralow drift without the use of high

power on-chip heaters.

The LT1021-7 uses no resistive divider to set output

voltage, and therefore exhibits the best long term stability

and temperature hysteresis. The LT1021-5 and LT1021-

10 are intended for systems requiring a precise 5V or 10V

reference with an initial tolerance as low as

±0.05%.
