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