Description

The HIP5600 is an adjustable 3-terminal positive linear voltage regulator capable of operating up to either 400VDC or 280VRMS. The output voltage is adjustable from 1.2VDC 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 HIP5600's 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 10mF for stability of the output and may require a 0.02mF 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.
