LM137/LM337

3-Terminal Adjustable Negative Regulators

n 77 dB ripple rejection

n Excellent rejection of thermal transients

General Description

The LM137/LM337 are adjustable 3-terminal negative volt-

age regulators capable of supplying in excess of −1.5A over

an output voltage range of −1.2V to −37V. These regulators

are 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 opti-

mized for excellent regulation and low thermal transients.

Further, the LM137 series features internal current limiting,

thermal shutdown and safe-area compensation, making

them virtually blowout-proof against overloads.

n 50 ppm/˚C temperature coefficient

n Temperature-independent current limit

n Internal thermal overload protection

n P⁺Product Enhancement tested

n Standard 3-lead transistor package

n Output is short circuit protected

LM137 Series Packages and Power

Capability

The LM137/LM337 serve a wide variety of applications in-

cluding local on-card regulation, programmable-output volt-

age regulation or precision current regulation. The LM137/

LM337 are ideal complements to the LM117/LM317

adjustable positive regulators.

Full output current not available at high input-output voltages

†

C1 = 1 µF solid tantalum or 10 µF aluminum electrolytic required for

stability

*C2 = 1 µF solid tantalum is required only if regulator is more than 4" from

power-supply filter capacitor

Output capacitors in the range of 1 µF to 1000 µF of aluminum or tantalum

electrolytic are commonly used to provide improved output impedance and

rejection of transients
