when the output voltage is 0.6V. A resistor-divider con-  
Detailed Description  
nected from OUT to GND produces higher output volt-  
ages and allows for a smaller output capacitor. The  
value of the output capacitor is inversely proportional to  
the output voltage:  
The MAX8515A/MAX8515 adjustable shunt regulators  
feature isolated supply inputs and outputs, ideal for isolat-  
ed power-supply applications using an optocoupler in the  
feedback path. The MAX8515A/MAX8515 sink 20mA with  
V
at 0.2V. The wide input supply range allows the  
OUT

VOUT = 0.6 × 1 +  
device to operate from 1.7V to 28V. The MAX8515A/  
MAX8515 compare the FB input to a precision 600mV  
reference. If the FB input is low, OUT sinks no current. If  
FB rises above 600mV, OUT sinks up to 20mA.

Applications Information  
Set the current limit with a resistor connected from IN to  
OUT. This type of shunt regulator is limited to low-current  
applications. The MAX8515A/MAX8515 can typically sink  
up to 20mA in this application.

Voltage Reference  
Figure 1 shows the MAX8515A/MAX8515 configured as a  
shunt regulator. Connect FB to OUT for an output voltage  
of 0.6V. Connect a 1.0µF capacitor from OUT to GND  
Figure 2 shows the test circuits for gain and phase plots.
