The RT8008-33 is a step-down DC-DC converter with a fixed output voltage of 1 2.5V, 5.5V, and 3.3V, and a rated current of 600mA. It is packaged as an SOT-23-5 and is RoHS compliant. The RT8008-33 is manufactured by Richtek, a company specializing in analog semiconductors. It is typically used in embedded systems, handheld devices, and computer peripherals as a means of converting the available input power into an acceptable operating voltage level for ICs working within the device. Its small size makes it ideal for space-constrained applications. The RT8008-33 also features a low dropout voltage, low quiescent current, and wide temperature range, making it a reliable and efficient choice.
