MJLM137-H REV 0A0
3-TERMINAL VOLTAGE REGULATOR,
VOLTS AT 0.5A
General Description
The LM137H is an adjustable 3-terminal negative voltage regulator capable of supplying in
excess of -0.5A over an output voltage range of -1.2V to -37V. This regulator is
exceptionally easy to apply, requiring only 2 external resistors to set the output voltage
and 1 output capacitor for frequency compensation. The circuit design has been optimized
for excellent regulation and low thermal transients. Futher, the LM137H features internal
current limiting, thermal shutdown and safe-area compensation, making it virtually
blowout-proof against overloads.
The LM137H serve a wide variety of applications including local on-card regulation,
programmable-output voltage regulation or precision current regulation. The LM137H is an
ideal complement to the LM117H adjustable positive regulator.
