Output current 1A and 0.5A at input voltage 10V

SII Semiconductor Corporation, a subsidiary of Seiko Instruments, will launch the S-19244/S-19243 series of LDO (low dropout) regulators in May.

The S-19244/S-19243 series offers a variety of options, including a soft-start function and high-temperature operation up to 125°C. These new LDO regulators offer a 10V input voltage and output currents of 1A and 0.5A. Target applications include automotive engine electronic control units (ECUs), body ECUs, meters, automotive cameras, automotive navigation systems, car audio systems, and automotive infotainment systems.

The S-19244/S-19243 series is available in eight product forms and five package options, allowing design engineers to select the optimal design based on their needs. These products are available with a choice of soft start (fixed/adjustable timing), discharge shunt (with or without), pull-down resistor (with or without), and fixed or externally supplied output voltage.

This series of products is available in a variety of package options ranging from high-dissipation packages such as TO-252-5S, HSOP-8A, HSOP-6, SOT-89-5, and HSNT-8(2030) to ultra-small packages.

Advanced driver assistance systems (ADAS) in modern automobiles require multiple cameras that operate at power levels below 10V. The S-19244/S-19243 series is ideally suited for these applications.

The soft-start feature stabilizes the input voltage before the device starts, thereby suppressing excessive inrush current and resulting output voltage transients, thereby enhancing device reliability. It also maintains a high output voltage accuracy of ±2.3%, regardless of temperature. AEC-Q100 qualification is currently underway, and PPAP (Production Part Approval Process) is available upon request.
