Specifically, it is useful in applications such as battery backup systems, automotive infotainment, notebook and tablet computers, portable devices, and power tools.

Working Principle

The TLV1117-15CKVURG3 voltage regulator employs a three-terminal adjustable regulator IC, which consists of two transistors, two resistors and a voltage reference, connected in series. During operation, the voltage reference and transistors combine to act as a voltage regulator. The voltage reference provides a fixed voltage of approximately 1.25 V for the output circuit. The two transistors, referred as pass transistors, act as a variable load on the input circuit. The two resistors create a voltage divider circuit on the input voltage and an adjustable output voltage is attained by controlling the current through the pass transistors. The device can be operated in the pulse frequency modulation (PFM) or pulse width modulation (PWM) mode. In the PFM mode, the pass transistors are operated at a single fixed frequency, while in the PWM mode they are operated at a variable frequency. In either mode, the device\'s impedance can be set by changing the value of the two resistors.

Advantages

The TLV1117-15CKVURG3 voltage regulator offers a variety of advantages compared to competitive products. It allows for an adjustable output from 1.25 V to 15 V with an input range of 2.7 V to 16 V. The voltage dropout is very low, making it ideal for battery-powered designs. The device also has very low quiescent current, up to 5.5 µA, making it a great choice for sleep mode applications. In addition, the excellent power efficiency and thermal performance of the device make it a great choice for the most demanding applications.

Conclusion

The TLV1117-15CKVURG3 voltage regulator is a high performance, low-dropout three-terminal adjustable linear voltage regulator from Texas Instruments.
