DESCRIPTION

The LM137 series are adjustable 3-terminal nega-

tive voltage regulators capable of supplying in ex-

cess - 1.5A over a - 1.2 to - 37V output voltage range.

They are exceptionally easy to use and require only

two external resistors to set the output voltage. Fur-

ther, both line and load regulation are better than

standard fixed regulators. Also, LM137 regulators

are supplied in standard transistor packages which

are easily mounted and handled. In addition to

higher performance than fixed regulators, the

LM137 series offer full overload protection available

only in integrated circuits. Included on the chip are

current limit, thermal overload protection and safe

area protection. All overload protection circuitry re-

mains fully functional even if the adjustment terminal

is disconnected.
