General Description
TS3480 series is an integrated linear voltage regulator . It can be prov ided 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 dev ices precludes their use. The TS3480 ser ies 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, v ery tiny 5V & 3.3V, 100mA bias supply that regulates directly off the sys tem pow er supply.

-150 -uVr ms COUT = 0.1uF, VIN = 10V Note 1: 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 perfor mance limits . For guaranteed perfor mance limits and associated tes t conditions, see the Electr ical Characteris tics Note 2: The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (Tj -Ta) / Rθja w here Tj is the junc tion temperature, Ta is the ambient temperature, and Rθja is the junction-to-ambient ther mal resis tance. The 350mW r ating results from subs tituting the absolute maximum o o junction temperature, 150 C for Tj, 50 C for Ta, and 300˚C/W for R θja. More pow er can be safely dissipated at lower ambient temperatures, and less power can be safely dissipated at higher ambient temperatures. The o o absolute maximum power dissipation can be increased by 3.5mW for each C below 50 C ambient. It mus t be o o derated by 3.5mW for each C above 50 C ambient. A Rθja of 300˚C /W represents the worst-case condition of no heat sinking of the 3-lead plas tic SOT-23 package. Heat s inking enables the safe dissipation of more o power. The TS3480 actively limits its junc tion temperature to about 150 C. Note 3: Times shown are dwell times. Temperatures shown are dwell temperatures. Note 4: For testing purposes, ESD was applied using the Human- Body Model, a 100pF capacitor discharged through a 1.5kΩ r esistor . o Note 5: A typical is the center of characterization data taken with Ta =Tj = 25 C. Typical are not guaranteed. Note 6: All limits are guaranteed. All elec trical characteristics hav ing room- temperature limits are tested during o production with Ta =Tj = 25 C . All hot and cold limits ar e guaranteed by correlating the electrical characteristics to process and temper ature variations and applying statis tical process control. Note 7: All voltages except dropout are with respec t to the voltage at the GND pin.
