3-Terminal Adjustable Regulator
General Description
The LM117HV are adjustable 3-terminal positive voltage reg-ulators capable of supplying either 0.5A or 1.5A over a 1.2V to 57V output range. They are exceptionally easy to u and require only two external resistors to t 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 ries 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 termi-nal is disconnected.
Normally, no capacitors are needed unless the device is sit-uated more than 6 inches from the input filter capacitors in which ca an input bypass is needed. An optional output ca-pacitor can be added to improve transient respon. The adjustment terminal can be bypasd to achieve very high ripple rejections ratios which are difficult to achieve with stan-dard 3-terminal regulators.
Besides replacing fixed regulators, the LM117HV is uful in a wide variety of other applications. Since the regulator is “floating” and es only the input-to-output differential volt-age, supplies of veral hundred volts can be regulated as long as the maximum input to output differential is not ex-ceeded, i.e. do not short the output to ground.
Also, it makes an especially simple adjustable switching reg-ulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM117HV can be ud as a precision current regulator. Sup-plies 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. Features
