LP5996SD-0833 is an innovative linear voltage regulator, which belongs to the PMIC – Voltage Regulators – Linear series. It utilizes the latest in integrated circuit technology and is designed to provide higher power output, better efficiency, and faster transient response than other traditional linear voltage regulators. This article explains the application fields and working principle of LP5996SD-0833.

Application Fields

LP5996SD-0833 is mainly used for sensitive applications such as digital/analog circuits, power supply design, automotive, medical and industrial applications. It can be used to reduce the current and voltage ripple, as well as providing a stable and reliable output voltage conditioning.

In automotive applications, it provides a stable and reliable voltage source for the vehicle’s Electronic Power Steering (EPS) system, which consists of two sets of rotary potentiometers. It can provide the EPS system with superior protection against overvoltage, overcurrent and thermal stress. It is also used in automotive infotainment systems to regulate audio noise and other input signals.

In medical applications, LP5996SD-0833 is used to control the output current of medical devices, like defibrillators, pacemakers and infusion pumps. It also provides a stable and reliable voltage source for medical equipment, such as blood glucose monitors, blood pressure monitors and other medical equipment.

In industrial applications, LP5996SD-0833 is used to control the voltage and current of motors, relays, solenoids and other components. It can also be used to regulate the power of light dimmers, temperature controls and other automated devices.

Working Principle

LP5996SD-0833 is a high performance and cost effective linear voltage regulator with adjustable output range, input voltage range and a wide operating temperature range. It works on the principle of voltage rectification, which is a process in which an alternating current is converted into a direct current (DC) through the use of components called diodes. The output voltage is then regulated and smoothed by an adjustable voltage regulator.

The LP5996SD-0833 features a built-in error amplifier with adjustable reference voltage and a feedback loop to control the output voltage. The output voltage is then regulated by the voltage regulator. The voltage regulator has two opposing transistors, an NPN and a PNP, with the PNP being the output transistor. The current across the two transistors is compared to the reference voltage and if it is higher or lower than the reference voltage, the transistor turns on or off, respectively. This controls and maintains the output voltage.

The voltage regulator also has an adjustable current limit circuit. This limits the maximum current through the regulator, thus, protecting the circuit and the components connected to it from over-current conditions. The regulator also has thermal protection and short-circuit protection which can shut down the output voltage if an over-temperature or short-circuit condition is detected.

Apart from the adjustable output range, the LP5996SD-0833 also features an internal synchronous rectifier which provides a more efficient conversion of the input voltage to the output voltage, allowing for a higher output current and a more efficient operation. It also features an integrated reference which helps reduce the power dissipation, allowing for lower operating temperatures.

Overall, the LP5996SD-0833 is a cost effective and efficient linear voltage regulator, which is ideal for sensitive applications such as digital/analog circuits, power supply design, automotive, medical and industrial applications. It features adjustable output range, input voltage range, wide operating temperature range and an internal synchronous rectifier for efficient voltage conversion. It also features built-in error amplifier with adjustable reference voltage, adjustable current limit circuit, and protection against over-temperature and short-circuit conditions.
