| TS3480 Low Quiescent Current LDO Voltage Regulator SOT-23 Pin Definition: 1. Output 2. Input 3. Ground 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. Features 30V maximum input for operation 2V guaranteed maximum dropout over full load and temperature ranges 100mA guaranteed minimum load current 5% guaranteed output voltage tolerance over full load and temperature ranges -40 to +125C junction temperature range for operation Ordering Information Part No. Package Packing TS3480CXxx RF SOT-23 3Kpcs / 7" Reel Note: Where xx denotes voltage option, available are 50 = 5.0V 33 = 3.3V contact to factory for addition voltage option Application Tiny alternative to TS78LXX series and similar devices Tiny 5V5% to 3.3V, 100mA converter Post regulator for switching DC/DC converter Bias supply for analog circuits Block Diagram Absolute Maximum Rating (Ta = 25oC unless otherwise noted) (Note 1) Parameter Input Voltage Operating Input Voltage Output Current Range Power Dissipation (Note 2) Junction Temperature Operating Temperature Range Storage Temperature Range Lead Soldering Time (260 C) (Note 3) ESD (note 4) o Symbol VIN VOPER IOUT Pd TJ TOPER TSTG TSOLDER Limit 35 30 100 350 +150 -40 ~ +125 -65 ~ +150 4 2 Unit V V mA W o o o C C C Sec kV 1/5 Version: A07 TS3480 Low Quiescent Current LDO Voltage Regulator Electrical Specification (Ta = 25oC, unless otherwise specified.)

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 Note 2: The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (Tj -Ta) / Rja where Tj is the junction temperature, Ta is the ambient temperature, and Rja is the junction-to-ambient thermal resistance. The 350mW rating results from substituting the absolute maximum o o junction temperature, 150 C for Tj, 50 C for Ta, and 300C/W for Rja. More power 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 must be o o derated by 3.5mW for each C above 50 C ambient. A Rja of 300C/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 o power. The TS3480 actively limits its junction 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 1.5k resistor. 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 electrical characteristics having room-temperature limits are tested during o production with Ta =Tj = 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 7: All voltages except dropout are with respect to the voltage at the GND pin. 2/5 Version: A07 TS3480 Low Quiescent Current LDO Voltage Regulator Electrical Characteristics Curve Figure 1.
