PMIC- Voltage Regulators - LinearCases in which adjustable voltage regulators may be necessary include those involving a single or two supplies, or a mixed multiple that goes beyond two. Even if it’s just one supply being utilized, the voltage regulation board needs to be able to effectively manage heat dissipation while maintaining the correct amount of voltage, as well as being of the right size and having a secure contact point. For situations where temperature stability and minimization of harmonic distortion are of utmost importance, RT9166A-33GXL is an ideal solution for the application.Below is a description of the working principle of RT9166A-33GXL, and its application field.The RT9166A-33GXL is a low dropout (LDO) linear voltage regulator that features an adjustable output from 0.9V to 3.3V. Its input voltage range is from 2.0V to 5.5V and its maximum output current is 800mA. Its specifications also include an adjustable output voltage power-off condition, a reference accuracy of 0.5%, a minimum dropout voltage of 0.2V and a maximum operating temperature of 125oC.The RT9166A-33GXL is capable of regulating smaller currents with less output noise and good temperature stability, which is the primary reason why it is often used in system-level voltage regulation designs. This makes the RT9166A-33GXL an ideal candidate for application fields such as automotive, industrial control systems, battery-powered devices and portable devices. Additionally, RT9166A-33GXL’s low power consumption and low dropout voltage allow it to be an ideal solution for game consoles and digital entertainment products. The working principle of the RT9166A-33GXL is fairly simple. It starts by drawing current from the input voltage and sending it to the reference voltage, which is often referred to as the bandgap voltage. The output of the bandgap voltage is then compared to the output voltage of the adjustable regulator and sent to the comparator. When the output voltage is higher than the setpoint voltage, the control voltage will reduce the current flowing through the pass transistor. This in turn decreases the voltage across the resistor, causing a decrease in the output voltage. On the contrary, the control voltage will increase the current through the pass transistor if the output voltage is lower than the set point voltage, resulting in an increase in the output voltage. The RT9166A-33GXL also features an adjustable power off condition to reduce power losses and aid in energy conservation. Overall, the RT9166A-33GXL is an ideal choice for any situation where a low-dropout and adjustable voltage regulator is needed. It is capable of providing a wide range of voltage regulation from 0.9V to 3.3V, offering good temperature stability and allowing for energy conservation due to its adjustable power off condition. Furthermore, its low operating temperature and small size makes it a great fit for many applications such as automotive systems and battery-powered devices.
