LM137HV/LM337HV

3-Terminal Adjustable Negative Regulators

(High Voltage)

General Description

The LM137HV/LM337HV are adjustable 3-terminal negative

voltage regulators capable of supplying in excess of −1.5A

over an output voltage range of −1.2V to −47V. These regu-

lators are exceptionally easy to apply, requiring only 2 exter-

nal resistors to set the output voltage and 1 output capacitor

for frequency compensation. The circuit design has been op-

timized for excellent regulation and low thermal transients.

Further, the LM137HV series features internal current limit-

ing, thermal shutdown and safe-area compensation, making

them virtually blowout-proof against overloads.

The LM137HV/LM337HV serve a wide variety of applica-

tions

programmable-output voltage regulation or precision current

regulation. The LM137HV/LM337HV are ideal complements

to the LM117HV/LM317HV adjustable positive regulators.

Typical Applications

†

electrolytic are commonly used to provide improved output impedance and rejection of transients.

C1 = 1 µF solid tantalum or 10 µF aluminum electrolytic required for stability. Output capacitors in the range of 1 µF to 1000 µF of aluminum or tantalum

C2 = 1 µF solid tantalum is required only if regulator is more than 4" from power-supply filter capacitor.
