The RT8023 bines two low dropout (LDO) linear regulators and a step-down converter with an input voltage range of 2.6V to 5.5V.

Each output voltage is adjustable from 0.8V to 5V.

With independent Enable and PowerGood pins for each regulator, it is easy to control the power up sequence, which is important in some applications.

include high output accuracy, current limiting protection, and 40μs fast turnon time. The step-down converter is a 1.2MHz PWM, current mode converter. Its high switching frequency allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal power switches with low on-resistance increase efficiency and eliminate the need for external Schottky diodes. The converter can run at 100% duty cycle for low dropout operation that extends battery life in portable systems. Feat.
