Description

The LM117HVQML-SP adjustable 3-terminal positive voltage linear regulator is capable of supplying 0.5A over a 1.2-V to 57-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 LM117HVQML-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 lower voltage applications, the LM117QML-SP is a pin-to-pin drop-in replacement suitable for up to 41.25 V. For the negative complement, see the LM137QML-SP datasheet.
