1.5 A Adjustable Output,
Positive Voltage Regulator

The LM317 is an adjustable 3−terminal positive voltage regulator

capable of supplying in excess of 1.5 A over an output voltage range of

1.2 V to 37 V. This voltage regulator is exceptionally easy to use and
requires only two external resistors to set the output voltage. Further, it
employs internal current limiting, thermal shutdown and safe area
compensation, making it essentially blow−out proof.

The LM317 serves a wide variety of applications including local, on
card regulation. This device can also be used to make a programmable
output regulator, or by connecting a fixed resistor between the
adjustment and output, the LM317 can be used as a precision current
regulator.

Features

• Output Current in Excess of 1.5 A

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

APPLICATIONS INFORMATION

Basic Circuit Operation

The LM317 is a 3−terminal floating regulator. In

operation, the LM317 develops and maintains a nominal

1.25 V reference (V

) between its output and adjustment

ref

terminals. This reference voltage is converted to a
programming current (I

) by R1 (see Figure 17), and this

PROG

constant current flows through R2 to ground.

The regulated output voltage is given by:

Since the current from the adjustment terminal (I

represents an error term in the equation, the LM317 was
designed to control I

to less than 100 mA and keep it

Adj

constant. To do this, all quiescent operating current is
returned to the output terminal. This imposes the
requirement for a minimum load current. If the load current
is less than this minimum, the output voltage will rise.

Since the LM317 is a floating regulator, it is only the
voltage differential across the circuit which is important to
performance, and operation at high voltages with respect to
ground is possible.

External Capacitors

A 0.1 mF disc or 1.0 mF tantalum input bypass capacitor
(Cin) is recommended to reduce the sensitivity to input line
impedance.

The adjustment terminal may be bypassed to ground to
improve ripple rejection. This capacitor (C
ripple from being amplified as the output voltage is
increased. A 10 mF capacitor should improve ripple
rejection about 15 dB at 120 Hz in a 10 V application.

Although the LM317 is stable with no output capacitance,
like any feedback circuit, certain values of external

)

capacitance can cause excessive ringing. An output
capacitance (CO) in the form of a 1.0 mF tantalum or 25 mF
aluminum electrolytic capacitor on the output swamps this
effect and insures stability.

Protection Diodes

When external capacitors are used with any IC regulator
it is sometimes necessary to add protection diodes to prevent
the capacitors from discharging through low current points
into the regulator.

Figure 18 shows the LM317 with the recommended
protection diodes for output voltages in excess of 25 V or
high capacitance values (CO > 25 mF, C

> 10 mF). Diode

Adj

D1 prevents CO from discharging thru the IC during an input
short circuit. Diode D2 protects against capacitor C

Load Regulation

The LM317 is capable of providing extremely good load
regulation, but a few precautions are needed to obtain
maximum performance. For best performance, the
programming resistor (R1) should be connected as close to
the regulator as possible to minimize line drops which
effectively appear in series with the reference, thereby
degrading regulation. The ground end of R2 can be returned
near the load ground to provide remote ground sensing and
improve load regulation.
