LT3065EDD-2.5#PBF Application Field and Working Principle

The LT3065EDD-2.5#PBF belongs to the family of linear voltage regulators (PMIC – Voltage Regulators – Linear). It is a low-noise, low-dropout linear voltage regulator which provides ultra-low noise and high-accuracy output voltage. The LT3065EDD-2.5#PBF is designed to provide adjustable- or fixed-voltage outputs in applications such as digital audio. This article will discuss its application field and working principle.

Application Field

The LT3065EDD-2.5#PBF features a low-noise CMOS single-ended input and output, making it ideal for use in portable devices where power consumption is a concern. Its adjustable output voltage range of 2.5V to 17V makes it well suited for providing an adjustable output voltage from 3.3V to 12V, making it attractive for generating power supply for digital audio for solutions such as MP3 players and audio systems. The LT3065EDD-2.5#PBF also features a low quiescent current of 1.1mA and low dropout at full load, making it ideal for battery operated systems. The device features a very low noise of 0.25 μVrms and draws a very low quiescent current (1.1mA) at full load, making it an ideal choice for digital audio applications requiring a low-noise supply voltage.

Working Principle

The LT3065EDD-2.5#PBF works by using a low-noise CMOS single-ended input and output. The device uses high-frequency series PWM control to regulate the output voltage. The input voltage is converted to a digital value using analog comparators. This digital input value is used to generate a pulse width modulated (PWM) signal. This signal is then used to control the output voltage.The LT3065EDD-2.5#PBF also features a programmable logic block that allows users to adjust the output voltage set point and hysteresis. The hysteresis is set by a resistor connected to the ADJ pin. If a high value resistor is used, the LT3065EDD-2.5#PBF will regulate a higher output voltage, while a lower resistor value will result in a lower output voltage.

Conclusion

The LT3065EDD-2.5#PBF is a low-noise, low-dropout linear voltage regulator that provides adjustable- or fixed-voltage outputs for digital audio applications. Its low-noise and high-accuracy output as well as its low quiescent current and low dropout makes it ideal for battery operated systems such as portable digital audio devices. The LT3065EDD-2.5#PBF works by using high-frequency series PWM control to regulate the output voltage and can be adjusted according to the user’s preferences.
