The LP3874EMPX-3.3 is a three-terminal, low-dropout (LDO) linear voltage regulator with a maximum output of 3.3V. It is a linear voltage regulator, which is a form of integrated circuit commonly used in modern power management systems. This regulator is specifically designed to provide a precise amount of output voltage with a low dropout voltage, and it is capable of supplying up to 300mA of output current.

This product’s main application fields include cell phones and data card applications, and any other electronic device requiring a low voltage and/or low current LDO regulator. Low power, low noise, and high accuracy performance elements make the LP3874EMPX-3.3 a robust and reliable solution safeguarding the circuit and maintaining voltage stability in a wide range of electronic systems

The working principle of the LP3874EMPX-3.3 is essentially the same as other linear voltage regulators operating in the same environment. The device receives a certain amount of input power, typically embodied as an incoming electrical current, and then reduces the amount of energy necessary to form a desired output voltage from the system.

The LP3874EMPX-3.3 has a minimum input voltage of 1.8V and a maximum dropout voltage of 0.5V. The start-up time is typically 2msec, and the offset voltage is 3mV for output voltage ranges between 1.2V and 3.3V. Its temperature range of -40°C to +85°C allows this device to work under extreme operating conditions.

This linear voltage regulator works by diluting the input voltage with a high-priority resistor to a lower-priority one. This creates an operating differential between the resistor inputs and provides a reference voltage for the regulator output. This voltage reference determines the output voltage, which can be adjusted accurately with an external resistor divider.

The LP3874EMPX-3.3 has an internal power switch and a "shutdown" feature. Its internal current limiter prevents excessive current draw and its thermal shutdown feature guards against overheating. Its internal protection circuitry, including reverse-battery protection, short-circuit protection, current load protection, and thermal overload protection, provides protection against most head-on damage scenarios.

The LP3874EMPX-3.3 provides excellent quality with a high accuracy output voltage and low noise during transition. Its low operating current, low standby current and low dropout voltage gives it a distinct advantage over other linear voltage regulators.

In summary, the LP3874EMPX-3.3 is an ideal choice for low dropout voltage, low power applications requiring low voltage accuracy and stability. It is suitable for a wide range of applications, from cell phones and data cards to other low-current systems. Its superior performance, combined with its robust and reliable design, makes it a great option for powering today’s sophisticated electronic devices.
