LX432
Low Voltage Adjustable Precision Shunt Regulator
PRODUCTION DATA SHEET
TM
DESCRI PTI O N
The LX432 series are low-voltage
precision adjustable shunt regulators with
a reference voltage of 1.24V. The output
voltage may be set to any value between
1.24V and 20V by two external resistors.
These
devices
offer
low
output
impedance for improved load regulation –
typical output impedance is 200m
. The
LX432 series operates with an operating
current as low as 80A, making these
devices
suitable
for
portable
and
micropower applications.
Low voltage operation enables the
LX432 to be used in the feedback loop of
isolated low voltage power supplies. The
minimum output voltage is determined by
the LX432 output voltage plus the forward
voltage drop of the opto-coupler LED
(typically 1.24 + 1.4 = 2.64V minimum).
See figure 12.
The LX432 is offered in 3 lead SOT-23
or TO-92 packages, and is a drop-in
replacement for the TLV431 and SC431L
devices.
