CAT431L  
Low-Voltage Adjustable Precision Voltage Reference  
- 0.5% Tolerance  
- SOT23 and TO92 Packages  
- Low Startup Overshoot  
FEATURES  
Low startup overshoot  
Low dynamic impedance: 0.3at 1kHz  
Compact 3-lead SOT23 package option  
Industrial temperature range: -40°C to 85°C  
Adjustable output voltage: VREF to 6V  
Wide current operation: 40µA to 100mA  
Low temperature coefficient reference: +12mV  
max deviation over temperature  
Accurate 1.24V reference voltage: +0.5%  
(+6mV) at 25°C  
APPLICATIONS  
SMPS control loop  
Current limiting  
Shunt regulator  
Over/Under voltage monitor  
3V Off-line switching regulators  
Low temperature coefficient voltage reference  
DESCRIPTION  
Minimal overshoot at startup and wide AC bandwidth  
make the CAT431L easy to apply in a wide set of  
applications. When used with an opto-coupler, the  
CAT431L is an ideal voltage reference in isolated  
feedback circuits for 3V to 3.3V switch-mode power  
supplies.  
The CAT431L is a low-voltage three-terminal  
adjustable shunt voltage reference with guaranteed  
thermal stability over the industrial temperature range.  
The CAT431L has a lower 1.24V reference and wider  
operating current range than the widely used TL431  
and TL431A shunt-regulator references. Compared  
to the TLV431/A, the CAT431L 1.24V reference is two  
times more accurate.
