The TLV70025DDCR is a linear voltage regulator designed to deliver up to 2.5A of continuous current over a wide range of input voltages. It is a three-terminal, low-dropout (LDO) linear-regulator, capable of providing output voltage accuracy and low quiescent current. As a result, it can be used for system and battery-powered applications in low-power, portable computing and communications systems.

This linear voltage regulator is specifically designed for adjustable and fixed output voltage applications up to 5.5V, with a wide input voltage range from very low voltages, such as 1.2V, up to 6V. A power-OK output will indicate the presence of an output voltage greater than 1.8V.

The TLV70025DDCR also has an internal thermal shutdown switch, which prevents device damage due to high ambient temperatures and long-term exposure to high power loads. Additionally, a wide range of safety features keep the device safe in a wide range of environmental conditions.

The application fields of the TLV70025DDCR voltage regulator include the portable electronic devices, industrial equipment, automotive electronic systems, medical devices, and consumer electronic products. This device can be used to deliver power to processors, digital signal processors, logic circuits, microcontrollers, displays, digital amplifiers, memory cells, audio or video signal circuits, and power management circuits.

The working principle of the TLV70025DDCR voltage regulator is as follows. Upon start-up, the voltage regulator will sense the voltage of the input power source and output it at the specified level. Internally, the regulator uses transistors to pass the current through the resistors when the output voltage is lower than the input voltage. When the output voltage reaches the desired level, the transistors shift the current flow to regulate the voltage to the output. The amplifier comparator integrated in the device continuously compares the output voltage with the reference voltage from the band gap circuit.

The output voltage is also protected against over-voltage faults by an integrated current limit. If a fault or over-voltage condition is sensed, the integrated error amplifier in the device will trip the input current limit circuit, which shuts off the device. This process helps to protect circuit components from damage due to the over-voltage condition.
