Product Summary

The LM317LZ is an adjustable 3-terminal positive voltage regulator. The LM317LZ is capable of supplying 100mA over a 1.2V to 37V output range. Also, the LM317L is available packaged in a standard TO-92 transistor package which is easy to use.

Parametrics

LM317LZ absolute maximum ratings: (1) Power Dissipation: Internally Limited; (2) Input-Output Voltage Differential: 40V; (3) Operating Junction Temperature Range: -40 to +125°C; (4) Storage Temperature: -55 to +150°C; (5) Lead Temperature (Soldering, 4 seconds) : 260°C.

Features

LM317LZ features: (1) Adjustable output down to 1.2V; (2) Guaranteed 100mA output current; (3) Line regulation typically 0.01%V; (4) Load regulation typically 0.1%; (5) Current limit constant with temperature; (6) Eliminates the need to stock many voltages; (7) Standard 3-lead transistor package; (8) See AN-1112 for micro SMD considerations.
