Automotive LDO Regulators

ROHM's BD9xxN1 series (BD950N1G-C, BD933N1G-C, BD900N1G-C, BD950N1WG-C, BD933N1WG-C, and BD900N1WG-C) is optimized for primary (direct connection to 12 V) power supplies in a wide range of applications, including powertrain, body systems, advanced driver assistance systems (ADAS), and car infotainment. In recent years, the digitization of all types of equipment has been increasing the number of electronic components, which in turn has driven the demand to reduce the number of capacitors used for circuit stabilization to shrink both the size and the bill of material (BOM). This requires power supply ICs in power supply circuits that can achieve stable operation with small-sized capacitors, which has been difficult to achieve until now. ROHM’s BD9xxN1 series automotive LDO regulators achieve stable operation in applications with output capacitances of 1 μF or less.

Applications

• Powertrain (i.e., fuel injection) and tire pressure monitoring systems (TPMS)
• Body systems (e.g., body control modules)
• ADAS (e.g., domain controllers, ECUs, zonal processing)
• Car infotainment, including instrument clusters and head-up displays (HUD)
• Wide variety of applications in addition to automotive primary power supply systems
