Seiko Instruments Inc. never stops innovating. Just recently, the Japanese company has launched the S-19200 Series automotive LDO regulator with high input voltage of 50V, adopting a new compact package TO-252-5S (6.5 x 6.5 x t1.3 mm) with high heat dissipation.
The TO-252-5S can be mounted on the existing pad area of the TO-252-5 (DPAK) and offers almost the same heat dissipation, while realizing a mounting height reduction of around 50 percent and area reduction of 35 percent. Seiko also offers a more compact HSOP-6 package (6.0 x 5.02 x t1.75 mm) that is capable of high heat dissipation. This IC works suitably for automotive ECUs, and its usual applications include power supply for automotive interior electrical applications such as car audio systems, car navigation systems, accessories, ITS, headlights, car body, etc.
The S-19200 Series was particularly developed to meet the high quality requirements for automotive use. The operating temperature range up to 125 degrees C° and the 50V maximum input voltage enable operations in high temperature and high input voltage applications. Additionally, the current consumption is 4.0 μA typ, during operation. The outstanding load response characteristics enable this IC to be used in applications with huge load fluctuations.
The input voltage range is 3.0V to 50V and the output voltage is selectable from 2.0V to 15.0V in 0.1V steps. The regulator’s output accuracy is ±1.0% (Tj=+25 degree C), and a ceramic capacitor of 0.1 μF or more can be utilized for both input and output capacitors. Extra features include ON/OFF circuit, thermal shutdown circuit, and overcurrent protection circuit. What’s more, the package is safe as it is halogen-free and lead-free.
In order to ensure customers’ satisfaction and help them choose the right package options, Seiko offers a thermal simulation service for the S-19200 Series.
