Description
The GM1431 is a three terminal adjustable shunt regulator
with thermal stability guaranteed over temperature. Output
voltage can be adjusted to any value between 2.5V (V
)
ref
and 36V by using two external resistors. The GM1431 has
a typical dynamic output impedance of 0.2W. Active output
circuitry provides a very unique turn on characteristic, mak-
ing the GM1431
an excellent tum on replacement for
zener diodes in many applications such as onboard regula-
tion and adjustable power supplies. The GM1431 is an
ideal voltage reference for 3.0 to 3.3V switching power sup-
plies.
The GM1431 shunt regulator is available with 3 voltage tol-
erances, 0.5%, 1.0% and 2.0% over T = 0°C to + 70°C,
A
and four package options (SOT-23, TO-92, SOT-89 and
SOP-8). Whatever your application is, the GM1431 offers
the optimum combination of performance, reliability, and
economy.
