The TD221ID is a special purpose voltage regulator belonging to the PMIC (Power Management Integrated Circuit) family of integrated circuits. It is designed to provide a stable and regulated output voltage from an unregulated input voltage, protecting both the device itself and the equipment it is connected to from voltage fluctuations and surges.

The TD221ID has an operating voltage range of +4V to +20V, making it ideal for use in a wide variety of applications where a regulated output voltage is required. Its design also makes it well-suited for applications with high voltage and current requirements.

The TD221ID is a four terminal device with a pair of symmetric control terminals and a voltage regulator feedback loop. The two control terminals are used to set the output voltage, while the feedback loop is used to measure the actual output voltage and adjust the current flow through the two control terminals in order to maintain the desired output voltage. The device also features thermal protection, overvoltage and short-circuit protection, as well as an adjustable current limit.

The TD221ID also features an open loop amplifier, which is used to isolate the load from the voltage regulator. This isolation helps prevent interference and errors in the measurement of the actual output voltage, as well as protecting against overloads. The device also features an LED indicator to indicate when the device is powered, as well as a selectable input power on/off switch.

The TD221ID is well-suited for a variety of applications that require a precise and stable voltage output, such as high precision power supplies, DC converters, voltage regulators and battery trickle charges, as well as linear and switching power supplies. It is also suitable for use in a variety of industrial applications and automotive applications, such as electric and hybrid vehicles.

The TD221ID is a great choice for those needing a reliable, precise, and cost-effective voltage regulator solution. Its advanced features and robust design make it an ideal choice for demanding applications that require a precise and stable output voltage, while its flexible voltage range and adjustable current limit make it well-suited for a variety of applications.
