PRODUCTION DATA SHEET

The LX432 series are low-voltage Low voltage operation enables the precision adjustable shunt regulators with LX432 to be used in the feedback loop of
a reference voltage of 1.24V. The output isolated low voltage power supplies. The voltage may be set to any value between minimum output voltage is determined by
1.24V and 20V by two external resistors. the LX432 output voltage plus the forward

These devices offer low output voltage drop of the opto-coupler LED
impedance for improved load regulation typically + = 2.64V minimum .
typical output impedance is The See figure

LX432 series operates with an operating The LX432 is offered in 3 and 5-Pin
