LM3411  
Precision Secondary Regulator/Driver  
other types of voltage regulators or power semiconductors to  
provide a precision output voltage without precision resistors  
or trimming.  
General Description  
The LM3411 is a low power fixed-voltage (3.3V or 5.0V) pre-  
cision shunt regulator designed specifically for driving an op-  
toisolator to provide feedback isolation in a switching regula-  
tor.  
Features  
n Fixed voltages of 3.3V and 5.0V with initial tolerance of  
The LM3411 circuitry includes an internally compensated op  
amp, a bandgap reference, NPN output transistor, and volt-  
age setting resistors.  
±
±
1% for standard grade and 0.5% for A grade  
n Custom voltages available (3V–17V)  
n Wide output current range, 20 µA–15 mA  
n Low temperature coefficient  
n Available in 5-lead SOT23-5 surface mount package  
(tape and reel)  
A trimmed precision bandgap reference with temperature  
drift curvature correction, provides a guaranteed 1% preci-  
sion over the operating temperature range (A grade version).  
The amplifier’s inverting input is externally accessible for  
loop frequency compensation when used as part of a larger  
servo system. The output is an open-emitter NPN transistor  
capable of driving up to 15 mA of load current.  
Applications  
n Secondary controller for isolated DC/DC PWM switching  
regulators systems  
n Use with LDO regulator for high-precision fixed output  
regulators  
n Precision monitoring applications  
n Use with many types of regulators to increase precision  
and improve performance  
Because of its small die size, the LM3411 has been made  
available in the sub-miniature 5-lead SOT23-5 surface  
mount package. This package is ideal for use in space criti-  
cal applications.  
Although its main application is to provide a precision output  
voltage (no trimming required) and maintain very good regu-  
lation in isolated DC/DC converters, it can also be used with
