RT9059GQW

The RT9059GQW from Richtek is a 3A, ultra low dropout (LDO) voltage regulator in 10 pin WDFN package. It 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 device 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. It is typically used in notebook PC applications and motherboard applications.

• Supply input voltage range from 1V to 5.5V, output current up to 3A
• High accuracy ADJ voltage of 1.5%
• Dropout voltage of 350mV at Iout = 3A typically
• VOUT power good signal
• VOUT pull low resistance when disable
• Current limiting protection
• Thermal shutdown protection
• 3V to 5.5V control voltage, VDD (VDD <gt/> Vout + 1.5V)
• Quiescent current of 0.6mA (En on, no load)
• Ambient temperature range from -40°C to 85°C
