ROHM offers 24 models in a range of different speeds, power consumption's, packages, and channels to ensure compatibility with a wide variety of sets. 1.8V drive and input/output full swing operation result in efficient driving.

Original precision technology and unique device construction enables simultaneous low VF and IR along with high ESD resistance.

Optimising switching speeds has resulted in a power supply efficiency of 91%. This translates to a 140mW difference at 9V/200mA, or roughly equivalent to the amount of power consumption reduction of 10 conventional op amps.

A variety of lineups are offered optimized for compact, energy-saving power supply configurations, including high accuracy (±1%) units and models integrating multiple protection circuits (i.e. over voltage, over current,temperature protection).

In order to minimize power consumption the power supply system must operate efficiently at high frequencies. ROHM's DC/DC converters integrate a power MOSFET with low ON resistance utilizing DMOS processes for high-speed switching capability, reducing power consumption.

Even when small currents are superimposed, the load on a battery may become large. In response to this we offer a 30µA low noise current regulator developed using original circuit technology that integrates a P-channel DMOSFET as the output transistor.
