LM3480 100 mA, SOT-23, Quasi Low-Dropout Linear Voltage Regulator

Check for Samples: LM3480

FEATURES

DESCRIPTION

The LM3480 is an integrated linear voltage regulator.

It features operation from an input as high as 30V

and a ensured maximum dropout of 1.2V at the full

100 mA load. Standard packaging for the LM3480 is

the 3-lead SOT-23 package.

•

3.3, 5, 12, and 15V Versions Available

Packaged in the Tiny 3-Lead SOT-23 Package

APPLICATIONS

•

Tiny Alternative to LM78LXX Series and

Similar Devices

The 5, 12, and 15V members of the LM3480 series

are intended as tiny alternatives to industry standard

LM78LXX series and similar devices. The 1.2V quasi

low dropout of LM3480 series devices makes them a

nice fit in many applications where the 2 to 2.5V

dropout of LM78LXX series devices precludes their

(LM78LXX series devices) use.

•

Tiny 5V±5% to 3.3V, 100 mA Converter

Post Regulator for Switching DC/DC Converter

Bias Supply for Analog Circuits

KEY SPECIFICATIONS

The LM3480 series features a 3.3V member. The

SOT-23 packaging and quasi low dropout features of

the LM3480 series converge in this device to provide

a very nice, very tiny 3.3V, 100 mA bias supply that

regulates directly off the system 5V±5% power

supply.

•

30V Maximum Input for Operation

1.2V Ensured Maximum Dropout Over Full

Load and Temperature Ranges

•

100 mA Ensured Minimum Load Current

±5% Ensured Output Voltage Tolerance Over

Full Load and Temperature Ranges

•

−40 to +125°C Junction Temperature Range for

Operation
