RT9053AGB Description

Short technical summary and product information.

The RT9053AGB from Richtek Technology is a versatile linear low-dropout (LDO) voltage regulator designed for various power management applications. It offers an adjustable output voltage with a minimum of 0.8V and a maximum of 5.15V, capable of supplying up to 400mA of current. The device features a low quiescent current of 50 µA, making it suitable for power-sensitive designs.

 

Key electrical characteristics include a maximum input voltage of 5.5V and a low voltage dropout of just 0.35V at 400mA. The regulator includes over-current and over-temperature protection features for enhanced reliability. Its PSRR is rated between 56dB and 35dB across the 1kHz to 10kHz frequency range.

 

The RT9053AGB is available in a surface-mount SOT-23-5 package, specifically identified as SC-74A or SOT-753. This small footprint makes it ideal for space-constrained applications. The operating temperature range is from -40°C to 85°C, ensuring performance in diverse environmental conditions. The device also features an enable control input for power sequencing or shutdown capabilities.
