RT9059GSP [RICHTEK]

The RT9059 is a high-performance positive voltage regulator designed for applications requiring very low input voltage and very low dropout voltage at up to 3A. It operates with a VIN as low as 1V and a 3V VDD, with a programmable output voltage as low as 0.8V. The RT9059 features ultra-low dropout, making it ideal for applications where VOUT is very close to VIN. Additionally, the RT9059 has an enable pin to further reduce power dissipation during shutdown. The RT9059 provides excellent regulation over variations in line, load, and temperature. It also provides a power-good signal to indicate if the voltage level of VOUT reaches 90% of its rated value.
