FUNCTION
Power Ground. Connect PGND and GND together.
Analog Ground. Connect GND and PGND together.
Output. Connect a ceramic capacitor from OUT to GND. See the Applications Information section.
Supply Input. Connect a 0.1μF capacitor to GND.
Feedback Input. Regulates to 600mV.
Detailed Description
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
when the output voltage is 0.6V. A resistor-divider con-
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:
V OUT = 0 . 6 × ? 1 +

V OUT at 0.2V. The wide input supply range allows the
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
Shunt Regulator/Adjustable
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
? 0 . 6 ?
? V OUT ?
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.
Figure 2 shows the test circuits for gain and phase plots.
