DESCRIPTION  
KEY FEATURES  
   Low Voltage Operation: 1.24V Reference  
   Initial Voltage Reference Accuracy 1%  
   Adjustable Output Voltage From VREF To 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  
250m. 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.  
APPLICATIONS  
   Low Voltage Adjustable Power Supplies
