DESCRIPTION
The LM117HV are adjustable 3-terminal positive
voltage regulators capable of supplying either 0.5A or
1.5A over a 1.2V to 57V output range. They are
exceptionally easy to use and require 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 series 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 rejections ratios
which are difficult to achieve with standard 3-terminal
regulators.
Besides replacing fixed regulators, the LM117HV is
useful 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.
