Single Channel CMOS LDO Regulators

ROHM Semiconductor Single Channel CMOS LDO Regulators are high-performance regulators with low current consumption that comes mounted in different package options. These LDO regulators feature high-accuracy output voltage, high ripple rejection, and compatibility with small ceramic capacitors. The CMOS LDO regulators offer excellent noise and load response characteristics despite its low circuit current consumption. Additional features include a built-in Over Current Protection Circuit (OCP) and a built-in Thermal Shutdown Circuit (TSD). These LDO regulators are most appropriate for various applications such as power supplies for logic IC, RF, and camera modules.
