The RT9169-26GB is a high efficiency low-dropout (LDO) linear voltage regulator. Whiles its primary purpose is to provide a steady regulated output voltage based on a reference voltage, the device can also supply large current without heat sinking and also provide excellent line, load and temperature stability. It is suitable for scenarios where a stable voltage output with low noise is needed and also where space saving and cost effectiveness are major factors.

General Description of the Application Field and Working Principle of the RT9169-26GB

The RT9169-26GB can be mainly employed as a post-regulator to provide a steady output voltage. It supports an input voltage range of 1.2V to 5.5V and an output voltage of 0.8V to 4.4V. It is capable of supplying up to 1.2A with an output voltage accuracy of +/-0.5%. Its features include short circuit protection, fast transient response, low power consumption, low dropout voltage and high output voltage accuracy.

The operation of the RT9169-26GB follows a simple procedure. The operation is based on a two-stage process in which the input voltage is converted into the output voltage via two transistors and a voltage reference. The voltage reference provides a constant voltage and is used as a reference for the output voltage. When the output voltage of the device is greater than the voltage reference, the input voltage is converted into the output voltage. The output voltage is then adjusted and adjusted accordingly to match the voltage reference. The output voltage is then further regulated through a feedback loop where the output voltage is compared to the reference voltage. The output voltage is then adjusted to match the voltage reference.

One of the most advantageous features of the RT9169-26GB is its very low quiescent current which is just 40 µA. This makes it suitable for many battery-operated applications where the battery life is crucial. The device also provides excellent line, load and temperature stability, making it a great choice for applications that require a high degree of output voltage accuracy. Furthermore, the device is also very cost effective, making it ideal for applications where cost is a major factor.
