RT9020-18GU5 Description

Short technical summary and product information.

The RICHTEK RT9020-18GU5 is a linear voltage regulator designed for various electronic applications. It features a fixed output voltage of 1.8V and can supply up to 500mA of current. The device operates within a temperature range of -40°C to 85°C.

 

Key electrical characteristics include a maximum input voltage of 5.5V and a low quiescent current of 50 µA. It also offers a Power Supply Rejection Ratio (PSRR) of 55dB at 10kHz. Protection features such as over current and over temperature protection are integrated for enhanced reliability.

 

The regulator is supplied in a surface-mount SC-70-5 package, also known as 5-TSSOP or SOT-353. This small footprint makes it suitable for space-constrained designs. The control features include Enable and Soft Start functions, allowing for controlled power-up sequences.
