description/ordering information

INPUT

The LM317L is an adjustable three-terminal

positive-voltage regulator capable of supplying

100 mA over an output-voltage range of 1.2 V to

32 V. It is exceptionally easy to use and requires

only two external resistors to set the output

voltage.

OUTPUT

ADJUSTMENT

In addition to higher performance than fixed

regulators, this regulator offers full overload

protection, available only in integrated circuits. Included on the chip are current-limiting and thermal-overload

protection. All overload-protection circuitry remains fully functional, even when ADJUSTMENT is disconnected.

Normally, no capacitors are needed unless the device is situated far from the input filter capacitors, in which

case an input bypass is needed. An optional output capacitor can be added to improve transient response.

ADJUSTMENT can be bypassed to achieve very high ripple rejection, which is difficult to achieve with standard

three-terminal regulators.

In addition to replacing fixed regulators, the LM317L regulator is useful in a wide variety of other applications.

Since the regulator is floating and sees only the input-to-output differential voltage, supplies of several hundred

volts can be regulated as long as the maximum input-to-output differential is not exceeded. Its primary

application is that of a programmable output regulator, but by connecting a fixed resistor between

ADJUSTMENT and OUTPUT, this device can be used as a precision current regulator. Supplies with electronic

shutdown can be achieved by clamping ADJUSTMENT to ground, programming the output to 1.2 V, where most

loads draw little current.

The LM317LC is characterized for operation over the virtual junction temperature range of 0°C to 125°C.
