The LP5951MF-3.3/NOPB is a versatile voltage regulator with a wide variety of application fields. This voltage regulator can be used in consumer electronics, such as LED light drivers and portable device power supplies, automotive applications, such as engine control systems, airbag systems and navigation systems, industrial automation, such as PLCs and data loggers, and communication systems.

The Working Principle of the LP5951MF-3.3/NOPB is quite straightforward. The voltage regulator uses an internal voltage reference and return-to-zero error amplifier, which compares the 3.3V output voltage to the reference voltage. When the input voltage rises above the reference voltage, the return-to-zero error amplifier reduces the output current to ensure a constant 3.3V output voltage. The device also includes a drain follower current limiting circuit which limits the output current in the event of an over-current condition.

The LP5951MF-3.3/NOPB also features input and output trim pins which can be used to trim the line drop and line tug to help reduce EMI and output noise. The input trim pin adjusts the input offset voltage and the output trim pin adjusts the short circuit current. The device also features a low quiescent current of 1.2mA, making it well suited for battery-powered applications.

The LP5951MF-3.3/NOPB is the ideal voltage regulator for a wide range of applications. With excellent transient and thermal stability, low ESR output capacitor capability, low RON outputs, and a wide operating temperature range, this device is a great choice for consumer, automotive, computer, industrial and communications applications.
