GL431
2.5V ADJUSTABLE SHUNT REGULATOR
Description
The GL431 is a three terminal adjustable shunt regulator
with thermal stability guaranteed over temperature.
Output voltage can be adjusted to any value between
2.5V (Vref) and 36V by using two external resistors. The
GL431 has a typical dynamic output impedance of 0.2
ohm. Active output circuitry provides a very unique turn on
characteristic, making the GL431 an excellent replac-
ement for zener diodes in many applications such as on-
board regulation and adjustable power supplies. The
GL431 is an ideal voltage reference for 3.0 to 3.3V swi-
tching power supplies.
The GL431 shunt regulator is available with 3 voltage to-
lerances 0.5% and 1.0% over TA=0°C to +70°C , and four
package options (SOT-23 and TO-92) .Whatever your ap-
plication is , the GL431 offers the optimum combination of
performance, reliability, and economy.
