Introduction

LP2988IMMX-3.0/NOPB from Texas Instruments is a 3-channel, low-dropout linear voltage regulator (LDO), designed for extended battery life and low noise, using a wide input voltage range of 2.5V to 26V, and a low quiescent current of 400 nA. The LP2988IMMX-3.0/NOPB provides excellent output voltage accuracy of ±1% over the full-temperature range (+125°C).

Application Field

The LP2988IMMX-3.0/NOPB is a versatile voltage regulator that can be used in a wide range of applications, such as the automotive industry. Automotive electronics have a need for high current, low voltage regulation and the LP2988IMMX-3.0/NOPB presents a great alternative for automotive system designers, where small size and low Vin to Vout is a must.LP2988IMMX-3.0/NOPB can also be used in industrial and medical applications, where high reliability and space-savings are key requirements. The LP2988IMMX-3.0/NOPB will provide a reliable, low noise supply for the medical systems, that can operate up to 26V input voltage.Finally, the LP2988IMMX-3.0/NOPB can be used in a wide range of consumer electronics and IoT applications, such as security cameras, wireless router, and smart home appliances. The low dropout voltage, low noise, and wide temperature range will make it suitable for these applications.

Working Principle

The LP2988IMMX-3.0/NOPB is a three-channel, low dropout linear voltage regulator (LDO) for high current, low voltage regulation. It uses an internal P-Channel as pass element, this makes it more suitable for of low-current, high-voltage applications than other discrete alternatives.An internal voltage reference is key part of the device functioning, it provides excellent output voltage accuracy over the full-temperature range (+125°C). The internal P-Channel is controlled via a gate width modulator (GWM) that allows the users to set each of the three different channels to different voltage levels. The LP2988IMMX-3.0/NOPB also offers protection features, such as thermal shutdown and output current limit. These features protect both the LP2988IMMX-3.0/NOPB and the system itself in case of any fault.

Conclusion

The LP2988IMMX-3.0/NOPB is a versatile, low-dropout voltage regulator that can be used in a wide range of applications. The internal P-Channel and the wide input voltage range of 2.5V to 26V, make it ideally suited for automotive electronics and other high current, low voltage regulation applications. The excellent output voltage accuracy of +1%, and the low quiescent current of 400 nA, make the LP2988IMMX-3.0/NOPB a great choice for designers who require optimised efficiency and noise performance in their system.
