Features • 3.3, 5, 12, and 15V versions available • Packaged in the tiny 3-lead SuperSOT package 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 SuperSOT® 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 applications 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 packaging 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. Key Specification • 30V maximum input for operation • 1.2V guaranteed maximum dropout over full load and temperature ranges • 100 mA guaranteed minimum load current • ±5% guaranteed output voltage tolerance over full load and temperature ranges • -40 to +125°C junction temperature range for operation Applications • Tiny alternative to LM78LXX series and similar devices • Tiny 5V±5% to 3.3V, 100 mA converter • Post regulator for switching DC/DC converter • Bias supply for analog circuits

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
