TS3480

Low Quiescent Current LDO Voltage Regulator

1/5

Version: A07

SOT-23

General Description

TS3480 series is an integrated linear voltage regulator. It can be provided the operation from an input as high as 30V

and a guaranteed maximum dropout of 1.2V at the full 100mA load. The 1.2V quasi low dropout of TS3480 series is

able to makes them a nice fit in many applications where the 2 to 2.5V dropout of TS78LXX series devices precludes

their use.

The TS3480 series features a 5V & 3.3V member. The SOT packaging and quasi low dropout features of the TS3480

series converge in this device to provide a very nice, very tiny 5V & 3.3V, 100mA bias supply that regulates directly off

the system power supply.
