The automotive LDO regulator IC series equipped with Nano Cap™ technology developed by Rohm Co., Ltd. enables stable operation even with extremely small output capacitor capacitance.

Rohm announced the development of the 'BD9xxN1 series' (BD950N1G-C, BD933N1G-C, BD900N1G-C, BD950N1WG-C, BD933N1WG-C, BD900N1WG-C) automotive LDO regulator IC, which is optimized for primary power supplies in automotive applications.

As the number of electronic components required in all devices increases, there is a growing demand for reducing capacitors, which are widely used in circuit stabilization, in order to achieve miniaturization and reduce the number of components.

Rohm stated, "While it has been difficult for the industry to achieve stable operation as required by applications with output capacitor capacitance of 1µF or less, we have productized an LDO regulator that realizes stable operation even with extremely small output capacitor capacitance based on the power IC stability control technology 'Nano Cap™' established in 2020."

The 'BD9xxN1 series' supports extremely small output capacitor capacitance of 100nF, which is 1/10 or less of standard products, and achieves stable operation required by applications even during input voltage and load current fluctuations.

It can support a wide range of output capacitor capacitance from standard several µF small MLCCs (multilayer ceramic capacitors) and large-capacity electrolytic capacitors to extremely small 0603-size MLCCs of 1µF or less, contributing not only to miniaturization of components and PCBs but also to reduced design workload by satisfying a wide range of capacitor specifications.

Meanwhile, Rohm added that it will expand the lineup of this series equipped with Nano Cap™ by adding 22 products in 2022 and 24 products in 2023, for a total of 46 products.
