LP3856ET-3.3 is a low-cost, high efficiency, low-drop-out voltage regulator. It is designed according to the typical features of linear PMIC (Power Management Integrated Circuits) voltage regulators. LP3856ET-3.3 is a very-low-dropout (VLDO) voltage regulator, which has a wide input voltage range, low quiescent current and extended temperature range, making it a great choice for many applications. It also offers excellent transient response with high PSRR (power supply rejection ratio) performance.

The LP3856ET-3.3 linear PMIC voltage regulator is suitable for a wide variety of applications, from consumer electronics to industrial grade systems. It can be used in applications such as low voltage power supplies, sub battery systems, automotive power systems and voltage regulation for microprocessors, microcontrollers and other digital circuits. As the LP3856ET-3.3 is a low-drop out regulator, it can also be used in low-noise audio or video applications. It can also be used in 3-pin, 4-pin and 5-pin packages.

LP3856ET-3.3 has a wide 2.3V to 6V input voltage range and delivers 1.3A output current. The regulator features an adjustable output voltage from 2.2V to 5.5V, with a line regulation of 0.016V/V ±1%, and a load regulation of 0.5% ±1%. It has a low quiescent current of 4μA (typical) at no load, which makes this device very effective in battery-powered applications. Other features of LP3856ET-3.3 include low dropout voltage, excellent transient response, high PSRR performance and exceptional noise immunity.

The working principle of LP3856ET-3.3 is based on an inductor-based voltage conversion technique. This technique allows for a low-dropout voltage with high power efficiency, thus making it suitable for use in low-power systems. The device contains an error amplifier, two PMOS transistors, an inductor and an output capacitor. The PMOS transistors act as switches, and they allow the energy stored in the inductor to be transferred to the output capacitor, depending on the voltage difference between the LF and the output. The error amplifier monitors the voltage difference between the output and the LF, and adjusts the PMOS transistors to maintain a stable output.

The regulator has a wide operating temperature range of -40°C to +125°C, making it suitable for use in the harshest of environments. Also, the device features under-voltage lockout and thermal protection circuitry that ensures the device is protected against any possible abuse. The LP3856ET-3.3 is available in an SOT-23-5 package, allowing for simple and compact design.

The LP3856ET-3.3 PMIC low dropout regulator is an excellent choice for many applications, due to its wide input voltage range, low quiescent current and extended temperature range, as well as its excellent transient response and high PSRR performance. It also has a number of features such as under-voltage lockout and thermal protection, which make it easy to use and reliable in the toughest of environments.
