DESCRIPTION

KEY FEATURES

Low Voltage Operation: 1.24V Reference

Initial Voltage Reference Accuracy 1%

Adjustable Output Voltage From V_REFTo 20V

Typical Output Dynamic Impedance Less

Than 250mΩ

Sink Current Capability 80µA To 20mA

Direct Alternative To TLV431

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

250mΩ. The LX432 series operates with

an operating current as low as 80µA,

making these devices suitable for por-

table and micropower applications.

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.
