PMIC - Voltage Regulators - Linear

LP2950ACZ-5.0/LFT1 is a Programmable Micropower Voltage Regulator that simply offers drop-in replacement and superior performance in a wide range of applications.

It is designed to provide the highest level of accuracy combined with the highest current load capabilities and exceptional load and line transients. It is an ideal power source for analog and digital circuits and has superior performance over the standard three-terminal regulator.

The LP2950ACZ-5.0/LFT1 offers extremely low noise and exceptional transient response, making it suitable for low voltage, high current and high efficiency applications. The LP2950ACZ-5.0/LFT1 also features a low quiescent current and an adjustable output current limit. The device can be configured to provide either fixed or adjustable output voltage.

The LP2950ACZ-5.0/LFT1 is designed to provide extremely low noise, high load transient response and fast recovery time. It is rated to provide a maximum output voltage of 5 volts and a maximum output current of 2.5A. The device also has an adjustable output current limit and is designed to provide high efficiency, low power dissipation, and excellent thermal stability.

Application field:

• Used in Local Area Network (LAN) devices
• Widely used in consumer electronics such as TV, DVD, digital media players, and other consumer audio/video equipment
• Used in chargers for portable consumer electronics such as smartphones and tablets
• Used in LED lighting and LED displays
• Used in portable medical devices, battery operated instruments and other portable consumer electronics

Working principle:

The LP2950ACZ-5.0/LFT1 voltage regulator provides a regulated output voltage by sensing the input voltage and adjusting the output accordingly. It does so by controlling the amount of current flowing through the regulator. When the output voltage falls below the specified level, the regulator increases the current, thus increasing the output voltage. The reverse happens when the output voltage is above the specified level.

The device also has a built-in current limiting feature which limits the output current when the current limit condition is reached. The regulator then reduces the output voltage until the current limit condition is no longer reached. The current limit feature is adjustable and can be set to suit the requirements of the application.

The LP2950ACZ-5.0/LFT1 also has a wide input range of 3.3V to 44V, so it is suitable for applications where the input voltage is not fixed. The regulator has a wide temperature range and can operate in temperatures from -40°C to 125°C. It also provides a high load transient response, so it is suitable for applications with large load transients.

The LP2950ACZ-5.0/LFT1 also has an overvoltage protection feature which shuts down the regulator if the input voltage exceeds the specified level. This prevents any damage to the device, as the regulator will not continue to operate when the input voltage is too high.

The LP2950ACZ-5.0/LFT1 also has an excellent noise performance and provides very low noise, which makes it ideal for high performance and low noise applications. The device provides a low quiescent current and is an ideal power source for analog and digital circuits.
