3 Description
The LMx17HV is an adjustable 3-terminal positive
voltage regulator capable of supplying 1.5 A or more
currents over a 1.25-V to 57-V output voltage range.
It requires only two external resistors to set the output
voltage. The LMx17HV is packaged in standard
transistor packages that are easily mounted and
handled.
The LMx17HV offers overload protection like current
limit, thermal overload protection and safe area
protection, which make the device blowout proof. The
overload protection circuitry remains fully functional
even if the adjustment terminal is disconnected.
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
which are difficult to achieve with standard 3-terminal
regulators.
Since the regulator is floating and sees only the input-
to-output differential voltage, supplies of several
hundred volts can be regulated as long as the
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.
*Needed if device is more than 6 inches from filter
capacitors. .
