TPS2100DBVR

The TPS2100DBVR is a voltage regulator and OR controller from Texas Instruments. It is a low-dropout linear regulator that provides adjustable 1.25V to 15V outputs. The device features a high efficiency low-noise switched-mode controller with a DC/DC power factor correction, allowing supplies up to 25V to be regulated with a short response time and safe operation. As an OR controller, the device features fast control signals with a minimum on-resistance of 35 mOhms, making it suitable for hot-swap, point-of-load, and bidirectional OR applications. With the low-noise switched-mode controller and the fast control signals, the TPS2100DBVR is ideal for a wide range of applications including automotive, industrial, and medical.

TPS2100DBVR Application Field

The TPS2100DBVR can be used in a variety of applications. As a voltage regulator, the TPS2100DBVR is ideal for automotive applications where high efficiency and low-noise operation is required. The device can be used to regulate 24V supplies to 5V or 12V outputs. The TPS2100DBVR also features a hot-swap protection circuit which allows for safe operation when hot-swapping loads. Additionally, the device can be used as an OR controller for hot-swap or point-of-load applications. The hot-swap circuit allows for an instantaneous power up or down of the load and the OR controller allows for bidirectional current flow, making it suitable for battery charging applications.

TPS2100DBVR Working Principle

The working principle of the TPS2100DBVR is based on its two main features, the low-drop Linear Regulator and the high-efficiency OR controller. The Linear Regulator is used to provide a constant and stable output voltage to the load. The device contains an internal reference voltage source, an error amplifier, and an output transistor which are used to regulate the output voltage. The OR controller is used to provide fast control of the output voltage. The OR controller is connected to the error amplifier and the output transistor which are used to control the switching of the output transistor. This allows for an instantaneous turn-on or turn-off of the output voltage and is used for hot-swap and point-of-load applications.
