LM137HV/LM337HV

3-Terminal Adjustable Negative Regulators

(High Voltage)

General Description

Features

n Output voltage adjustable from −1.2V to −47V

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.

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

n Line regulation typically 0.01%/V

n Load regulation typically 0.3%

n Excellent thermal regulation, 0.002%/W

n 77 dB ripple rejection

n Excellent rejection of thermal transients

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 short circuit protected

The LM137HV/LM337HV serve a wide variety of applica-

tions

including

local

on-card

regulation,

programmable-output voltage regulation or precision current

regulation. The LM137HV/LM337HV are ideal complements

to the LM117HV/LM317HV adjustable positive regulators.

Typical Applications

Adjustable Negative Voltage Regulator

DS009066-1

DS009066-25

†

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

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

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