LM3480 100 mA, SOT-23, Quasi Low-Dropout Linear Voltage Regulator
March 2005
LM3480
100 mA, SOT-23, Quasi Low-Dropout Linear Voltage
Regulator
General Description
The LM3480 is an integrated linear voltage regulator. It
features operation from an input as high as 30V and a
guaranteed maximum dropout of 1.2V at the full 100 mA
load. Standard packaging for the LM3480 is the 3-lead Su-
perSOT
®
package.
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 appli-
cations where the 2 to 2.5V dropout of LM78LXX series
devices 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
5V
±
5% power supply.

Note 1:
The package code MA03B is internal to National Semiconductor Corporation and indicates a specific version of the SOT-23 package and associated
mechanical drawings.
Note 2:
The suffix “I” indicates the junction temperature range for operation is the industrial temperature range, −40 to +125˚C. The suffix “M3” indicates the die is
packaged in the 3-lead SOT-23 package. The suffix “X” indicates the devices will be supplied in blocks of 3k units as opposed to blocks of 250 units.
Note 3:
Because the entire part number does not fit on the SOT-23 package, the SOT-23 package is marked with this code instead of the part number.
Note 4:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics tables.
Note 5:
The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (T
J
- T
A
)/θ
JA
where T
J
is the junction
temperature, T
A
is the ambient temperature, and
θ
JA
is the junction-to-ambient thermal resistance. The 333 mW rating results from substituting the Absolute
Maximum junction temperature, 150˚C, for T
J
, 50˚C for T
A
, and 300˚C/W for
θ
JA
. More power can be safely dissipated at lower ambient temperatures. Less power
can be safely dissipated at higher ambient temperatures. The Absolute Maximum power dissipation can be increased by 3.33 mW for each ˚C below 50˚C ambient.
It must be derated by 3.33 mW for each ˚C above 50˚C ambient. A
θ
JA
of 300˚C/W represents the worst-case condition of no heat sinking of the 3-lead plastic SOT-23
package. Heat sinking enables the safe dissipation of more power. The LM3480 actively limits its junction temperature to about 150˚C.
Note 6:
Times shown are dwell times. Temperatures shown are dwell temperatures. For detailed information on soldering plastic small-outline packages, refer to
the
Packaging Databook
available from National Semiconductor Corporation.
Note 7:
For testing purposes, ESD was applied using the human-body model, a 100 pF capacitor discharged through a 1.5 kΩ resistor.
Note 8:
As with the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 250 mW rating
appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125˚C, for T
J
, 50˚C for T
A
, and 300˚C/W for
θ
JA
in
P = (T
J
- T
A
)/θ
JA
. More power can be dissipated at lower ambient temperatures. Less power can be dissipated at higher ambient temperatures. The maximum power
dissipation for operation appearing under Operating Ratings can be increased by 3.33 mW for each ˚C below 50˚C ambient. It must be derated by 3.33 mW for each
˚C above 50˚C ambient. A
θ
JA
of 300˚C/W represents the worst-case condition of no heat sinking of the 3-lead plastic SOT-23 package. Heat sinking enables the
dissipation of more power during operation.
Note 9:
A typical is the center of characterization data taken with T
A
= T
J
= 25˚C. Typicals are not guaranteed.
Note 10:
All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production with T
A
= T
J
= 25˚C. All hot and cold
limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 11:
All voltages except dropout are with respect to the voltage at the GND pin.
