SPX3819R2-L/TR is a low-dropout voltage regulator that is used in a wide range of applications. It has a wide operating voltage range from 2.5V to 5.5V and multiple output profiles ranging from 3.3V to 6V. The maximum output current of the device is 2.85A. SPX3819R2-L/TR is an ideal power Save-A-StepTM solution that allows a single output voltage to be provided with the same accuracy over its wide operating temperature range which makes it the perfect choice for space-constrained industrial, communication and consumer electronics.

SPX3819R2-L/TR belongs to the family of PMIC-Voltage Regulators-Linear. This kind of linear regulator is used for its high efficiency, less noise and a wide selection of output voltage and current. The device has an on-board voltage reference that provides stable output voltage even under transient conditions for maximum flexibility. It also has an adjustable soft start to prevent the output voltage from overshooting the set level and ensure a smooth startup sequence.

The device is designed to have low-dropout performance, meaning that only a small drop in the output voltage will occur when connected to an output voltage higher than the power supply voltage. The maximum drop-out voltage of the device is guaranteed to be less than 250 mV. This feature helps eliminate the need of an external low-dropout regulator when supplying the output voltage from a source with higher voltage than the required output voltage.

SPX3819R2-L/TR also has an overload protection feature which will immediately shut off the output in the event of an overload or short circuit condition. The device has an over-temperature protection feature which will shut off the output when it reaches a predetermined maximum temperature. This ensures that the device does not overheat and cause damage to itself or other components connected to it.

The device is also designed with an enable function, allowing the output to be quickly disabled when not in use. The device is RoHS compliant and comes in an SOT-23-5 SMT package. This package allows for a compact design, making the SPX3819R2-L/TR suitable for a variety of applications requiring low profile and space saving solutions.

In summary, the SPX3819R2-L/TR is a low-dropout regulator with wide operating voltage range, multiple output profiles and protection features such as over-temperature, overload and enable functions. The device is very efficient, reliable and suitable for various applications requiring low voltage and current in a space-constrained environment.
