1 Features 3 Description

The LM3480 is an integrated linear voltage regulator.

1• Input Voltage Range: up to 30 V

It features operation from an input as high as 30 V

• 3.3-V, 5-V, 12-V, and 15-V Versions Available and an ensured maximum dropout of 1.2 V at the full

• Packaged in the Tiny 3-Lead SOT-23 Package 100-mA load. Standard packaging for the LM3480 is

• 30-V Maximum the 3-lead SOT-23 package. Input for Operation

• 1.2-V Ensured Maximum Dropout Over Full Load The 5-V, 12-V, and 15-V members of the LM3480

and Temperature Ranges series are intended as tiny alternatives to industry

standard LM78Lxx series and similar devices. The • 100-mA Ensured Minimum Load Current

1.2-V quasi-low dropout of LM3480 series devices

• ±5% Ensured Output Voltage Tolerance Over Full makes them a nice fit in many applications where the

Load and Temperature Ranges 2-V to 2.5-V dropout of LM78Lxx series devices

• −40 to +125°C Junction Temperature Range for precludes their (LM78Lxx series devices) use.

Operation The LM3480 series also features a 3.3-V member.
