Description
The CBM317 is adjustable 3-terminal positive voltage regulator capable of supplying in excess of
1.5 A over an output voltage range of 1.25 V to 37 V. These voltage regulator is exceptionally
easy to use and require only two external resistors to set the output voltage.Further, it employ
internal current limiting, thermal shutdown and safe area compensation, making them
essentially blow-out proof.
The CBM317 serve a wide variety of applications to make a programmable output regulator, or
by connecting a fixed resistor between the adjustment and output, the CBM317 series can be
used as a precision current requlator.
