The LM117QML-SP 3-terminal positive voltage linear regulator is capable of supplying either 0.5 A or 1.5 A over a 1.2-V to 37-V output range. It is simple to use and requires only two external resistors to set the output voltage.
The regulator is "floating" and sees only the input-to-output differential voltage, thus enabling supplies of several hundred volts to be regulated as long as the maximum input-to-output differential is not exceeded.
The flight-proven LM117QML-SP offers full overload protection such as current limit, thermal overload protection, and safe area protection. It is exceptionally versatile and can also be used as an adjustable switching regulator, a programmable output regulator, a precision current regulator, and more.
For high voltage applications, the LM117HVQML-SP is a pin-to-pin drop-in replacement suitable for up to 60V. For the negative complement of the LM117QML-SP, see the LM137QML-SP.
