FEATURES

DESCRIPTIO

■

10µA to 20mA Operating Range

TheLM185-1.2isatwoterminalbandgapreferencediode

that has been designed for applications which require

precision performance with micropower operation. The

device provides guaranteed operating specifications at

currents as low as 10µA. The nominal voltage is 1.235V

with both 1% and 2% tolerances available. Some addi-

tional features are: maximum dynamic impedance of 1Ω,

low noise and excellent stability over time and tempera-

ture. Advanceddesign, processingandtestingtechniques

make Linear’s LM185-1.2 a superior choice over previous

designs. A micropower 5V reference application is shown
