TLV2217-25PWR is a three-terminal LDO Linear Voltage Regulator which is specially designed for the application field in low power and low voltage system for low power applications. It provides a clean and stable output voltage which is adjustable from 0.8V to 4.3V, with a maximum output current up to 25mA. Besides, it also contains current limit and thermal protection features, as well as very low Standby current.

TLV2217-25PWR employs an advanced bias current cancellation topology, which is specially designed to keep device operation within the safe operating area. This makes TLV2217-25PWR a great choice for system designers, who are looking for a low noise, low quiescent current and low drop out power solution.

The TLV2217-25PWR series provides up to 25mA output current, with a tight 0.5% voltage regulation. It can be used in a wide variety of systems, including battery operated systems, mobile devices, automotive applications, digital signal processing, industrial and consumer electronics.

The working principle of TLV2217-25PWR is based on the traditional three terminals linear regulator design. Basically, it contains an error amplifier, an additional voltage reference, and a pass transistor, which operates as a voltage divider. This design relies upon the principles of negative feedback and stability to maintain the output voltage constant, even when the input voltage varies.

The error amplifier compares the output voltage to its reference voltage. When the output voltage falls below its reference voltage, the error amplifier increases the applied current to the pass transistor, which in turn increases the voltage across the pass transistor. This extra current is then applied to the load, causing the output voltage to increase until it reaches the desired setting. Similarly, when the output voltage becomes too high, the error amplifier decreases the current applied to the pass transistor, thus reducing the output voltage.

TLV2217-25PWR also offers protection features over temperature, short circuit and load dump conditions to minimize system damages. With its advanced power management features, it can deliver the necessary power and flexibility for low-power applications.
