ZXRE250/ ZXRE252

VERY LOW CATHODE CURRENT

ADJUSTABLE PRECISION SHUNT REGULATOR

Description

Pin Assignments

The ZXRE250 and ZXRE252 are three-terminal adjustable shunt

regulators, offering excellent temperature stability and output current

handling capability up to 100mA. The output voltage may be set to

any chosen voltage between 2.5 and 36 volts by selection of two

external divider resistors.

REF

ANODE

ZXRE250 has the same electrical specifications as the industry

standard ‘431 except that it features a very low minimum cathode

current for regulation. The typical value of 40µA makes the parts ideal

for very low-power applications.

CATHODE

SOT23

The devices can be used as a replacement for zener diodes in many

applications requiring an improvement in zener performance. The

ZXRE250/2 is available in two grades with initial tolerances of 1% and

0.5% for the A and B grades respectively.
