LM3480

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

Regulator

General Description

Key Specifications

n 30V maximum input for operation

The LM3480 is an integrated linear voltage regulator. It fea-

tures operation from an input as high as 30V and a guaran-

teed maximum dropout of 1.2V at the full 100 mA load. Stan-

dard packaging for the LM3480 is the 3-lead SuperSOT^®

package.

n 1.2V guaranteed maximum dropout over full load and

temperature ranges

n 100 mA guaranteed minimum load current

5% guaranteed output voltage tolerance over full load

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

tended 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 appli-

cations where the 2 to 2.5V dropout of LM78LXX series de-

vices precludes their (LM78LXX series devices) use.

and temperature ranges

n −40 to +125˚C junction temperature range for operation

Features

n 3.3, 5, 12, and 15V versions available

n Packaged in the tiny 3-lead SuperSOT package

The LM3480 series features a 3.3V member. The SOT pack-

aging 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

Applications

n Tiny alternative to LM78LXX series and similar devices

5V 5% power supply.

n Tiny 5V 5% to 3.3V, 100 mA converter

n Post regulator for switching DC/DC converter

n Bias supply for analog circuits
