3 Description

The

LM337-N-MIL

is

an

adjustable

3-terminal

negative voltage regulator capable of supplying

−1.5 A or more currents over an output voltage range

of

−1.25 V to −37 V. It requires only two external

resistors to set the output voltage and one output

capacitor for frequency compensation. The circuit

design has been optimized for excellent regulation

and low thermal transients. Further, the LM337-N-MIL

features internal current limiting, thermal shutdown

and safe-area compensation, making it virtually

blowout-proof against overloads.

The LM337-N-MIL is an ideal complement to the

LM117 and LM317 adjustable positive regulators.

Adjustable Negative Voltage Regulator

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
