Rohm says the BD9xx N1 series achieves the performance needed for high densities in smaller form factors with stable operation even with small capacity capacitors of 1µF or less.
There are 18 regulator ICs in the series which have an output three times higher than previously available. The ICs also have low output ripple of approximately 250mV and load current variation of 1mA to 500mA within 1µs, with a low capacitance of 470nF (typical).
The power ICs are available in five package options, HTSOP-J8 (4.9 x6.0x1.0mm), TO252-3 (6.5×9.5×2.5mm), TO252-5 (6.5×9.5×2.5mm), T)263-3 (10.16×15.10×4.7mm) and TO263-5 (10.16×15.1×4.7mm).
According to the company, they support standard small MLCCs (multi-layer ceramic capacitors) down to ultra small MLCCs e.g., 0603M (0.6×0.3mm) with capacities below 1µF. They are also suitable for large-capacity electrolytic capacitors.
The LDO regulator ICs are available directly from Rohm Semiconductor and online distributors DigiKey, Mouser and Farnell.
There are also Spice models available for simulation which can be downloaded from the company website.
Typical applications in automotive equipment are powertrain system power supplies for fuel injection and tyre pressure monitoring systems as well as body system power supplies for body control modules and infotainment system power supplies.
In industrial equipment, they can be used in power supplies for PLCs, remote terminal units and industrial gateways, and power supplies for monitor and control panels.
They are also suitable for power supplies in consumer electronics, for example in control boards for domestic appliances as well as thermostats and doorbells and power supplies for home security and network equipment.
