Secondary LDO Regulators

In today's world, where electronic devices feature increased functionality, greater miniaturization, and improved energy conservation, the use of power supply configurations utilizing local (secondary) power supplies is becoming more widespread. Thus, there is a demand for more stable power supplies with lower noise levels that enable more efficient driving of low voltage devices. ROHM offers high-accuracy fixed output secondary LDO regulators with shutdown switch featuring stable voltage supply and low noise levels in a compact package and are compatible with ceramic output capacitors, allowing them to be mounted in a small area. This makes them ideally suited for use in portable devices.
