MNLM117HV-H REV 2A1 MICROCIRCUIT DATA SHEET
POSITIVE THREE TERMINAL HIGH VOLTAGE ADJUSTABLE
REGULATOR
General Description
The LM117HV adjustable 3-terminal positive voltage regulator is capable of supplying in
excess of 0.5A over a 1.2V to 57V output range. It is exceptionally easy to use and
requires only two external resistors to set the output voltage. Further, both line and
load regulation are better than standard fixed regulators.
In addition to higher performance than fixed regulators, the LM117HV offers full overload
protection available only in IC's. Included on the chip are current limit, thermal
overload protection and safe area protection. All overload protection circuitry remains
fully functional even if the adjustment terminal is disconnected.
Normally, 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.
Besides replacing fixed regulators, the LM117HV is usefull in a wide variety of other
applications. 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, (i.e. do not short the output to
ground).
Also, it makes an especially simple adjustable switching regulator, a programmable output
regulator, or by connecting a fixed resistor between the adjustment and output, the
LM117HV can 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
1.2V where most loads draw little current.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Ratings indicate conditions for which the device is functional, but do not
guarantee specific performance limits. For guaranteed specifications and test
conditions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade
when the device is not operated under the listed test conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is
dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to
ambient thermal resistance), and TA (ambient temperature). The maximum allowable
power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number
given in the Absolute Maximum Ratings, whichever is lower.
Note 3: Human body model, 1.5K Ohms in series with 100pF.
