LT1963ET#31PBF

Application Field

The LT1963ET#31PBF can be used in a wide variety of applications that require low dropout and low noise performance, such as tablet PC, portable audio, wireless communication systems and precision control systems. It also can be used in a multi-input voltage environment, allowing it to be used in applications with different supply voltages. For example, in a multi-input voltage environment, it can provide output voltages of 5V, 9V, 10V and 12V, while having a dual input of 5V and 12V.

The LT1963ET#31PBF combines low noise and low output voltage with low dropout voltage and low quiescent current in a 10-lead TSOT package. All of these features make the LT1963ET#31PBF an ideal solution for any applications requiring high performance, low power consumption and exceptional output accuracy.

Working Principle

The LT1963ET#31PBF is a low-dropout linear voltage regulator. It operates by regulating the output voltage of the circuit to a predetermined value, which is set by a resistive divider network connected to the output terminal of the LT1963ET#31PBF. In order for the LT1963ET#31PBF to regulate the output voltage, it must draw a certain amount of current from the input voltage, which is referred to as the quiescent current. The quiescent current is controlled by the current sensing circuit in the LT1963ET#31PBF.

The current sensing circuit is designed to detect the amount of output current that flows through the regulator and adjust the quiescent current accordingly. When the maximum output current is exceeded, the regulator shuts down to protect the connected load. The voltage regulator also features thermal shutdown, which will protect the device when the internal temperature exceeds a predetermined value.

Additionally, the LT1963ET#31PBF offers ideal diode control, which helps reduce quiescent current when the desired output voltage is not reached and allows for fast transient response. The LT1963ET#31PBF also offers improved accuracy and stability over temperature, making it an ideal choice for applications requiring high performance and low noise.

Conclusion

The LT1963ET#31PBF is an excellent choice for applications requiring low dropout, low noise, low quiescent current and improved output accuracy over temperature. It features a variety of protection features, such as output current limit, thermal shutdown and ideal diode control, making it an ideal solution for any application requiring high performance, low power consumption and exceptional output accuracy.
