RT9011-GSGQW is a low power, high performance Linear Voltage Regulator (LDO) from Richtek Technology Corporation. With its great efficiency and low noise regulators, this series offers the highest cost performance and reliability for a wide range of applications. It is a perfect choice for powering small size loads in space-constrained systems, such as mobile for cellular phones, digital cameras, and multimedia applications.

The RT9011-GSGQW is a three-terminal positive voltage regulator which provides a regulated output voltage from 1V to 6V. It features a wide operating voltage range of up to 18V and high conversion efficiencies up to 95%. Additionally, the Dropout Voltage of this series is adjustable with an external resistor, making this regulator highly suitable for battery-powered applications.

The RT9011-GSGQW features an ultra-low quiescent current (Iq) of 0.65uA typical and 0.9uA maximum, making it an excellent choice for battery powered applications. The device utilizes an external resistor to set the output voltage. It has an advanced cutting-edge technology that supports high ESD level of 2KVHBM. The package of RT9011-GSGQW is available in QFN-3, SOT-23-5, and SOT-89, making it ideal for integrating into space-constrained applications.

The RT9011-GSGQW is designed to work within an ambient temperature range of -40°C to +85°C. This regulator also features an Over-Temperature Protection (OTP) circuitry, which shuts off the output during the excessive temperature. The OTP minimizes the output latching current, thus increasing the reliability and protection of the system.

The RT9011-GSGQW is a linear voltage regulator, meaning it is based on the principle of linear control. It works by taking in a signal voltage, typically from a power supply, and then regulating it to the desired voltage level. The output voltage is held constant by a feedback loop that monitors and compares the input signal and the output voltage, and then adjusts the regulating element (such as the amplifier or transistor) to the desired output. The regulating element is variously referred to as thepass element or main element, and is typically an amplifier or transistor, depending on the type of regulation.

The RT9011-GSGQW also features Low-Dropout voltage, which is slightly higher than the output voltage, making this regulator highly efficient. Additionally, it also has a thermal shutdown and an output overcurrent protection. The output overcurrent protection feature limits the current to a safe level when the power supply is unexpectedly overloaded. The thermal shutdown feature protects the regulator from damaging temperatures.

The RT9011-GSGQW is the perfect solution for low-noise, high-performance applications in mobile, automotive, and telecommunications markets. With its great efficiency and low power consumption, it offers the best cost-performance and reliability for a wide range of applications.
