Introduction

The LP38692MP-ADJ/NOPB is a micropower voltage regulator that is specially designed for use in portable systems where high efficiency and low power dissipation are critical design elements. This device can provide a regulated output of up to 1.5A while consuming only 6µW of quiescent current. It achieves this high efficiency by utilizing BiCMOS architecture, which combines BiCMOS and CMOS processes to reduce power consumption while still maintaining high voltage regulation accuracy. The LP38692MP-ADJ/NOPB is suitable for a wide range of applications, such as automotive, industrial, and consumer electronics.

Application Field

The LP38692MP-ADJ/NOPB is a micropower voltage regulator that can provide a regulated output of up to 1.5A. It features a maximum dropout voltage of only 1.2V and a wide input voltage range from 2.5V to 32V. With a wide input voltage range and low dropout voltage, this device is ideal for multiple power supply configurations and applications that have challenging input voltage conditions. This device is also optimized for low power consumption and can provide up to an 80% power savings over traditional linear voltage regulators, making it suitable for a wide range of portable applications such as cellular phones, PDAs, portable media players, and other battery-powered devices. The LP38692MP-ADJ/NOPB can also be used in automotive applications such as electric power steering and brake systems, where it is might be necessary to operate over high ambient temperature range. It is also suitable for industrial applications such as motor control and factory automation systems that require high accuracy and high power efficiency. In consumer electronics applications, it can be used in digital circuit designs such as LED drivers, digital display drivers, or other logic circuits that require a low supply voltage. Additionally, this device can be used in medical equipment such as infusion pumps and patient monitors where power efficiency is also an important design element.

Working Principle

The LP38692MP-ADJ/NOPB is a linear voltage regulator that provides a regulated output voltage by using a series pass element to drop the input voltage to the desired level. This series pass element is driven by a control circuit that monitors the output voltage and adjusts the current through the pass element to maintain the correct output voltage. The LP38692MP-ADJ/NOPB features an adjustable output voltage, which can be easily set using two external resistors. The nominal output voltage can be set using one resistor and a tolerance of ±5% is provided in the off state by adjusting the other resistor. The device also features an adjustable output current limit, which can be set using an external current sense resistor.

Conclusion

The LP38692MP-ADJ/NOPB is a micropower linear voltage regulator that can provide a regulated output of up to 1.5A while consuming only 6µW of quiescent current. It features an adjustable output voltage and output current limit, making it suitable for a wide range of applications such as automotive, industrial, and consumer electronics. Additionally, the device is optimized for low power consumption and can provide up to an 80% power savings over traditional linear voltage regulators, making it ideal for portable applications.
