LMx17HV High Voltage Three-Terminal Adjustable Regulator With Overload Protection
1 Features 3 Description
The LMx17HV is an adjustable 3-terminal positive

• Up to 60 V Input to Output Differential
voltage regulator capable of supplying 1.5 A or more
• 1.5-A Output Current
currents over a 1.25-V to 57-V output voltage range.
• Line Regulation 0.01%/V (Typical)
It requires only two external resistors to set the output
voltage. The LMx17HV is packaged in standard
• Load Regulation 0.1% (Typical)
transistor packages that are easily mounted and
• 80-dB Ripple Rejection (Typical)
handled.
• Internal Short-Circuit Current Limiting Protection
The LMx17HV offers overload protection like current

protection, which make the device blowout proof. The
(LM117HV)
overload protection circuitry remains fully functional
even if the adjustment terminal is disconnected.
• 0 to 125°C Operating Temperature Range

Typically, no capacitors are needed unless the device
is situated more than 6 inches from the input filter

capacitors, in which case an input bypass is needed.
An optional output capacitor can be added to improve

transient response. The adjustment terminal can be

bypassed to achieve very high ripple rejection ratios
• Factory Automation Systems
which are difficult to achieve with standard 3-terminal
regulators.
• Building Automation Systems
• Battery Charger
Since the regulator is floating and sees only the input-
to-output differential voltage, supplies of several
1.2-V to 50-V Adjustable Regulator With High
hundred volts can be regulated as long as the
Voltage Input
maximum input to output differential is not exceeded,
or in other words, do not short the output to ground.
By connecting a fixed resistor between the
adjustment and output, the LMx17HV can also be
used as a precision current regulator. Supplies with
electronic shutdown can be achieved by clamping the
adjustment terminal to ground, which programs the
output to 1.25 V where most loads draw little current.
