DESCRIPTION
KEY FEA TURES
s Low Voltage Operation: 1.24V Reference
s Initial Voltage Reference Accuracy 1%
s Adjustable Output Voltage From V
REF To 20V
s Typical Output Dynamic Impedance Less
Than 250m
s Sink Current Capability 80A To 20mA
s Direct Alternative To TLV431
Low voltage operation enables the
LX432 to be used in the feedback loop
of isolated low voltage power sup-
plies. 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 10.
The LX432 is offered in 3 and 5-pin
SOT-23 or TO-92 packages, and is a drop-
in replacement for the TLV431 and
SC431L devices.
The LX432 series are low-voltage pre-
cision 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 im-
pedance for improved load regula-
tion — typical output impedance is
250m
. The LX432 series operates with
an operating current as low as 80A,
making these devices suitable for por-
table and micropower applications.
