The RT9818C-20GV is a low dropout (LDO) 5.0V voltage regulator specifically designed for the field of PMIC (Power Management Integrated Circuit) supervisors. This device is capable of providing a regulated output voltage of 5.0V and a maximum output current of 20mA. The LDO regulator employs a built-in low voltage detector circuit. When the output voltage drops below a preset threshold (typically 4.6V), the “low” input pin is asserted and a “power fail” warning is sent to the CPU or microcontroller. The RT9818C-20GV, along with other devices in the family, are known to provide a high level of reliability and features a low ESR (equivalent series resistance). This is because the LDO regulator can operate down to 2.5V, making it ideal for low voltage applications.

In addition to providing a regulated output voltage of 5.0V, the RT9818C-20GV also has a built-in overvoltage protection (OVP) and can be used to protect system components from any excessive output voltages. As a result, the RT9818C-20GV is able to provide a safe and reliable power supply for system components.

The RT9818C-20GV also has a very low power consumption, with an integrated P-channel MOSFET and low on-resistance of 13mΩ. This makes it suitable for battery operated systems, where power consumption is critical. The RT9818C-20GV also has a fast transient response that helps ensure the output voltage remains within the preset tolerance range. This enables it to be used in demanding applications that require a fast and reliable response.

The RT9818C-20GV also features a wide input voltage range, allowing it to be used in a variety of applications. The device has an inductorless design, which reduces the number of components and makes the solution smaller and easier to maintain. Additionally, the RT9818C-20GV has low output noise, making it ideal for noise sensitive applications.

The RT9818C-20GV is available in a very small TSOT-23-6L package, which is ideal for storage and transportation. The device has an approximate idle current of only 420μA, and can be used in battery powered applications where power consumption is critical. Also, the device features a fast response time of 600μs, which helps it regain regulation quickly after a transient. Additionally, the RT9818C-20GV has internal short circuits protection, allowing it to shut down the output current in case of an overload.

In summary, the RT9818C-20GV is a low dropout 5.0V voltage regulator designed for power management supervisors. Its internal circuit provides protection against overvoltage and short circuit, and has a very low power consumption. The device also has an inductorless design, which offers a simpler and more reliable solution, and its wide input voltage range makes it suitable for a variety of applications. Finally, its small TSOT-23-6L package makes the RT9818C-20GV an ideal choice for storage and transportation.
