Thermally Protected High Voltage Linear
Regulator
The HIP5600 is an adjustable 3-terminal positive linear
voltage regulator capable of operating up to either 400V
DC
or 280V
RMS
. The output voltage is adjustable from 1.2V
DC
to within 50V of the peak input voltage with two external
resistors. This high voltage linear regulator is capable of
sourcing 1mA to 30mA with proper heat sinking. The
HIP5600 can also provide 40mA peak (typical) for short
periods of time.
Protection is provided by the on chip thermal shutdown and
output current limiting circuitry. The HIP5600 has a unique
advantage over other high voltage linear regulators due to its
ability to withstand input to output voltages as high as
400V(peak), a condition that could exist under output short
circuit conditions.
Common linear regulator configurations can be implemented
as well as AC/DC conversion and start-up circuits for switch
mode power supplies.
The HIP5600 requires a minimum output capacitor of 10µF
for stability of the output and may require a 0.02µF input
decoupling capacitor depending on the source impedance. It
also requires a minimum load current of 1mA to maintain
output voltage regulation.
All protection circuitry remains fully functional even if the
adjustment terminal is disconnected. However, if this
happens the output voltage will approach the input voltage.
