LP38693MPX-ADJ/NOPB

The LP38693MPX-ADJ/NOPB is an adjustable and fixed linear voltage regulator from Texas Instruments. It is an advanced version of the popular LP38693 (not the MPX version) and features a more versatile adjustable range and better thermal stability. The LP38693MPX-ADJ/NOPB is classified as a PMIC – Voltage Regulators – Linear, which indicates it provides a linear voltage regulation and is intended to be used with microprocessors and other digital ICs that require a stable power source.

The LP38693MPX-ADJ/NOPB is an adjustable solution that is capable of adjusting the output voltage within a range of 1.175 V to 5.5 V. This range is accomplished through an external resistor divider and a control pin that can be used to adjust the output voltage by a few tenths of a volt. The LP38693MPX-ADJ/NOPB also has a fixed version, where no external resistor divider is required. The fixed version is capable of varieties between 1.5V and 5.5V, and provides a consistent output voltage regardless of changes to the input voltage.

The LP38693MPX-ADJ/NOPB features a low quiescent current of 1.5 uA, making it highly suitable for portable and low-power applications. The LP38693MPX-ADJ/NOPB can also operate at a wide input voltage range of 2.7 V to 36 V, making it suitable for a variety of applications. It feature a maximum output current of 900 mA, and a maximum dropout of 180 mV at 700 mA.

The LP38693MPX-ADJ/NOPB uses an advanced on-chip voltage reference, allowing it to achieve excellent line and load regulation that is independent of the output voltage. This helps to ensure that the output voltage is consistently regulated regardless of any changes to the input voltage, temperature, or load current. The reference voltage accuracy is also excellent, delivering an accuracy of 0.05%.

In terms of thermal stability, the LP38693MPX-ADJ/NOPB can deliver an output voltage that is stable to within 0.05% of its initial setting over the full operating temperature range. This temperature stability ensures that the output voltage is always reliable and consistent under different conditions. The LP38693MPX-ADJ/NOPB also uses thermal protect mechanisms to protect itself from damage due to over-temperature.

The LP38693MPX-ADJ/NOPB has a wide variety of features and functions, which make it an excellent choice for applications that require a stable power rail. Its adjustable version can be used to provide a wide range of output voltages, while its fixed version offers consistent and accurate output voltages. Its low quiescent current, wide input voltage range and excellent line and load regulation make it suitable for both high current and low current applications. Its thermal stability and protection safeguards ensure that the voltage regulator is operating reliably and that it is protected from temperature-related damage. Overall, the LP38693MPX-ADJ/NOPB is an excellent choice for applications such as IoT devices and embedded controllers that require precise voltage regulation.
