BD933M5EFJ-C (Under Development)
QuiCur™, Automotive 500mA 3.3V, Fixed Output LDO Regulators
The BD9xxM5-C series are linear regulators using the QuiCur™ topology designed as low current consumption products for power supplies in various automotive applications requiring a direct connection to the battery. These products are designed for up to 45V as an absolute maximum voltage and to operate until 500mA for the output current with low current consumption 9.5µA (Typ). These can regulate the output with a very high accuracy ±2.0%.
What is QuiCur™?
QuiCur™ is a combination of technologies that provides high-speed load response.

Supporting Information
Overview
The BD9xxM5-C incorporates original QuiCur™ high-speed load response technology that delivers excellent response characteristics to load current fluctuations. For example, the LDO can maintain output to within 100mV of set voltage even as the load changes between 0 and 500mA in 1μs (Rise time/Fall time). Furthermore, low 9.5µA (typ.) current consumption contributes to lower power consumption in automotive applications.
Application Examples
Suitable for a wide range of automotive applications such as ECUs that operate on vehicle primary power supply systems.
• Powertrain: Fuel Injection (FI), Tire Pressure Monitoring System (TPMS)
• Body systems: Body Control Modules
• Infotainment: Instrument Clusters, Head-Up Displays (HUDs)
