LM137QML

3-Terminal Adjustable Negative Regulators

General Description

Features

The LM137 are adjustable 3-terminal negative voltage regu-

lators capable of supplying in excess of −1.5A over an output

voltage range of −37V to −1.2V. These regulators are excep-

tionally easy to apply, requiring only 2 external resistors to set

the output voltage and 1 output capacitor for frequency com-

pensation. The circuit design has been optimized for excellent

regulation and low thermal transients. Further, the LM137 se-

ries features internal current limiting, thermal shutdown and

safe-area compensation, making them virtually blowout-proof

against overloads.

Output voltage adjustable from −37V to −1.2V

1.5A output current guaranteed, −55°C to +150°C

Line regulation typically 0.01%/V

■

Load regulation typically 0.3%

Excellent thermal regulation, 0.002%/W

77 dB ripple rejection

Excellent rejection of thermal transients

50 ppm/°C temperature coefficient

Temperature-independent current limit

Internal thermal overload protection

Standard 3-lead transistor package

Output is short circuit protected

The LM137 serve a wide variety of applications including local

on-card regulation, programmable-output voltage regulation

or precision current regulation. The LM137 are ideal comple-

ments to the LM117 adjustable positive regulators.
