Product Overview

The LM117H is an adjustable 3-terminal Positive Voltage Regulator, capable of supplying in excess of 1.5A over a 1.2 to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulations are better than standard fixed regulators. Also, the LM117 is packaged in standard transistor packages which are easily mounted and handled. In addition to higher performance than fixed regulators, the LM117 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-inch from the input filter capacitors in which case an input bypass is needed. An optional output capacitor can be added to improve transient response.
  • Specified maximum 0.3% load regulation
  • Specified 1.5A output current
  • Adjustable output down to 1.2V
  • Current limit constant with temperature
  • P+ Product enhancement tested
  • 80dB Ripple rejection
  • Short-circuit protection for output
  • Green product and no Sb/Br


Power Management
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
