3-Terminal Adjustable Regulator

The LM117HV LM317HV are adjustable 3-terminal positive voltage Regulators capable of supplying in excess of 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 Also, the LM117HV is packaged in standard Transistor packages which are easily mounted and handled.
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.
The LM117HVK STEEL and LM317HVK STEEL are packaged in standard TO-3 Transistor packages, while the LM117HVH and LM317HVH are packaged in a solid Kovar base TO-39 Transistor package. The LM317HVT uses a TO-220 plastic package. The LM117HV is rated for operation from -55C to +150C, and the LM317HV from 0C to +125C.
