ABLIC Introduces the World's Smallest Automotive 150mA LDO Regulators S-19251 Series

ABLIC S-19251

ABLIC Inc. announced the launch of S-19251 Series, the world’s smallest automotive LDO regulators.

The new S-19251 Series is the automotive LDO regulator featuring 150 mA output current, 5.5 V input voltage, 1.0 to 3.5 V output voltage, 20 μA current consumption, and the 105 °C operating temperature. The package is the world’s smallest HSNT-4(0808)B (0.8 × 0.8 × 0.41 mm) that meets the strong demand for increasingly smaller packaging, yet achieves the low current consumption of 20 μA. This IC is suitable for smaller automotive ECUs and typical applications include power supply for electrical applications of vehicle interior (meters, car bodies, headlights, ITS, accessories, car navigation systems, car audio systems, etc.).
