3A, Ultra-Low Dropout Voltage Regulator

RT9059

Update Alert Share

The RT9059 is a high performance positive voltage regulator designed for use in 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 VDD voltage 3V with programmable output voltage as low as 0.8V. The RT9059 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, it has an enable pin to further reduce power dissipation while shutdown. The RT9059 provides excellent regulation over variations in line, load and temperature. The RT9059 provides a power good signal to indicate if the voltage level of VO reaches 90% of its rating value.
