RT9161A-35GG

RT9161A-35GG Description

The RT9161A-35GG is a high-performance linear regulator designed by Richtek USA Inc., a leading manufacturer in the power management integrated circuit (PMIC) industry. This IC regulator is specifically designed to provide a fixed output voltage of 3.5V with a maximum output current of 500mA. It is optimized for applications requiring a stable and efficient power supply with minimal dropout voltage, ensuring reliable operation even under varying input conditions.

The RT9161A-35GG features a maximum input voltage of 12V, making it suitable for a wide range of power sources. Its dropout voltage is a mere 1V at 500mA, which is significantly lower compared to many similar regulators, allowing it to maintain regulation even when the input voltage is close to the output voltage. This feature is particularly beneficial in battery-powered applications where the input voltage may drop over time.

The regulator is housed in a surface-mount SOT223 package, which is compact and suitable for space-constrained designs. It also comes in a tape and reel (TR) packaging format, facilitating automated assembly processes. The RT9161A-35GG is designed with over-current and over-temperature protection features, ensuring robustness and reliability in various operating conditions.
