Highlights of the standard LDO regulators are shown on this slide. First, low saturation transistors are used at the output stage. Reducing power loss makes it possible to achieve an output with a lower input voltage than that of traditional linear regulators; which can contribute to increased energy savings. Having a lower saturation voltage also allows for the input voltage to drop a greater amount without disturbing the regulated output voltage. Second is a high power supply rejection ratio. Secondary regulators are often used to suppress the noise created by switched mode power supplies (SMPS); thus it is important to have high PSRR characteristics (the higher, the better). On average, ROHM’s LDO regulators provide ~55dB of rejection. Lastly, compared to industry standard 78 series regulators, ROHM’s LDOs offer a much lower dropout voltage rating. This low dropout voltage allows for the output voltage to be constant for a longer period of time, increasing the operational use of portable devices.
