PMIC - Voltage Regulators - Linear

The LMS1585AIS-3.3/NOPB is a low-dropout linear regulator designed to maintain an efficient, noise-free supply voltage. The device is ideal for applications requiring a stable output power supply with low power dissipation and low voltage precision.

The LMS1585AIS-3.3/NOPB operates from an input voltage range of 3.14V to 18V and is able to deliver up to 0.5A continuous output current over a temperature range of -40°C to 125°C. It features a low dropout voltage, typically 2.1V at 0.2A, and offers an adjustable output voltage range of 1.2V to 3.3V. Additionally, the device has an internal bias circuitry and a power saving auto-shutdown function.

Operation of this linear regulator is based on a simple feedback circuit design which senses the output voltage on the output terminal and compares it with the reference voltage. When the feedback voltage drops below the reference voltage, the internal pass transistor increases its current. The current is then delivered to the load, increasing the voltage on the output terminal until it matches the reference voltage.

This device is designed for use in a range of applications such as low-power/ultra-low-power systems, active filter circuits, signal processing, and telecommunications. It provides a wide range of stable output currents over a temperature range and is an excellent choice for applications requiring an adjustable or precise voltage output.

The LMS1585AIS-3.3/NOPB is designed to provide superior power supply performance in comparison to other linear regulators available on the market. It features excellent thermal efficiency, low output voltage ripple, and low noise, making it ideal for applications in harsh and extreme environments.

The device also features an adjustable output and a wide adjustment range, which enables designers to easily adjust the output voltage and current levels while maintaining the stability of the power supply. This versatile device is also protected against damage from overcurrent and overheating. Additionally, it has a power saving auto-shutdown mode which reduces the power consumption when the supply voltage is low.

In conclusion, the LMS1585AIS-3.3/NOPB is a highly efficient and reliable linear regulator. It offers an adjustable output voltage range and low power dissipation, which make it suitable for a variety of applications. The device is protected against damage from overcurrent and overheating and features an efficient auto-shutdown mode. Its excellent thermal efficiency, low output voltage ripple and low noise make it an ideal choice for efficient and reliable power supply in harsh and extreme environments.
