TO-252-2L Plastic-Encapsulate Voltage Regulators

LM317 Three-terminal positive voltage regulator

DESCRIPTION

This monolithic integrated circuit is an adjustable 3-terminal

positive voltage regulator designed to supply more than 1.5A

of load current with an output voltage adjustable over a 1.2

to 37V. It employs internal current limiting , thermal shut-down

and safe area compensation.

FEATURE

z Internal thermal overload protection

z Internal short circuit current limiting

Output

Ci is required when regulator is located an appreciable distance from power supply filter.

Co is not needed for stability , however, it does improve transient response.

Since IADJ is controlled to less than 100µA, the error associated with this term is negligible in most applications.
