HIP5600

Thermally Protected High Voltage Linear

Regulator

The HIP5600 is an adjustable 3-terminal positive linear

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 10

µF

for stability of the output and may require a 0.02

µF 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.
