ROHM Develops Automotive Primary LDOs

Leveraging Original QuiCur Technology to Achieve Industry-Leading Load Response Characteristics - Seite 2

The lineup will be expanded to comprise a total of 18 models by FY2024, including the TO252-3, TO252-5, and HRP5 packages.

Application Examples
Suitable for a wide range of automotive applications such as ECUs that operate on vehicle primary power supply systems, including: 

• Powertrain: Fuel injection, tire pressure monitoring system
• Body systems: Body control modules
• Infotainment: Instrument clusters, head-up displays

QuiCur High-Speed Load Response Technology
QuiCur is the name of ROHM’s proprietary ‘Quick Current’ high-speed load response circuit capable of maximizing load response characteristics (response performance) without causing instability in the feedback circuits of power supply ICs. Stable operation of the power supply IC is also possible with minimal output capacitance. And in the case of switching regulators, which are a type of power supply IC, it is possible to linearly adjust the capacitance and output voltage fluctuation to easily achieve stable operation even when the capacitance is changed due to specification changes, significantly reducing the number of person-hours required for power circuit design - both in terms of decreasing component count and ensuring stable operation.

Support Tools
ROHM Real Models are high accuracy SPICE models that utilize original model-based technology to faithfully reproduce the electrical and temperature characteristics of the actual IC, resulting in a perfect match between the IC and simulation values. This ensures reliable verification, contributing to more efficient application development, for example by preventing rework after prototyping.

Real Models are now available on ROHM’s website:
