Working Principle

The SPX3819S-L-2-5/TR is a linear regulator that operates from 1.6 volts to 5.5 volts. It uses a high-efficiency, low quiescent current P-Channel MOSFET as a switch element to generate a constant, adjustable output voltage. The input voltage is applied to the gate of the MOSFET, and when it is higher than the reference voltage, the MOSFET is turned on and current flows from the input to the output. When the input voltage is lower than the reference voltage, the MOSFET is turned off and no current flows. The output voltage can be adjusted by varying the reference voltage.

The SPX3819S-L-2-5/TR offers several unique features that make it an excellent choice for a wide range of low-voltage and low-power applications. It has a low drop-out voltage of only 0.15 Volts and a very low quiescent current of less than 20μA. It is also available in a variety of package options, including TO-92 and SOT-23, which makes it easy to integrate into any application. In addition, the SPX3819S-L-2-5/TR has a low thermal resistance package and a wide operating temperature range, making it an ideal choice for both commercial and industrial applications.

In summary, the SPX3819S-L-2-5/TR is an adjustable, low dropout and low power linear regulator designed for use in an array of electronic devices and automotive applications. It is a P-Channel device and is available in a variety of package options, making it ideal for low-voltage and low-current applications. The SPX3819S-L-2-5/TR has a low drop-out voltage, low quiescent current, and low thermal resistance making it an excellent choice for any application requiring precise voltage control.
