Introduction
LT1963AET-1.8#30PBF is a voltage regulator device designed by Linear Technology. It is part of their PMIC (Power Management Integrated Circuit) family, specifically in the Voltgae Regulators - Linear series. The LT1963AET-1.8#30PBF provides regulated output voltage within a wide range of input voltages and is designed to be operational over a wide output current range of 1.5A. The device is highly efficient with low quiescent current and does not need a minimum load current to regulate the output voltage.Application Field
The LT1963AET-1.8#30PBF is suitable for a wide range of applications including portable and desktop notebooks, PDAs, digital cameras, and LCD TVs. The device can be used to provide regulated voltage for systems that require low noise, low power consumption and high efficiency. It is also recommended for applications with high efficiency requirements, such as battery powered products and energy-saving sources.Implementation
The LT1963AET-1.8#30PBF has a typical dropout voltage of 300mV, meaning that when supplying an output voltage of 5V, the minimum input voltage will be 5.3V. By using a high efficiency voltage regulator, less current will be wasted, allowing the device to be used in applications where power efficiency is of great importance.The device features a 3-terminal fixed output voltage of 1.8V with an accuracy of ±2%. It has an adjustable voltage range of 1.22V to 20V, allowing it to be used to provide an output voltage of 5V, 3.3V, 1.8V, 1.5V and other voltages depending on the application.The LT1963AET-1.8#30PBF has a package of TO-263 and requires a minimum footprint size of only 3mm2, and the device supports low output voltage slew rates of up to 0.3V/µs.Working Principle
The working principle of the LT1963AET-1.8#30PBF is as follows:An input voltage is supplied to the device and it is regulated by the low dropout regulator and then output at the desired voltage. The input voltage is equal to or greater than the output voltage plus the dropout voltage. The device features an internal voltage reference and high-current switch that allows it to regulate the output current and voltage with very low noise and a high accuracy.When the input voltage is greater than the output voltage plus the dropout voltage, the LT1963AET-1.8#30PBF will activate the high-current switch, allowing current to flow from the input to the output and the output voltage to remain constant. When the input voltage is lower than the output voltage plus the dropout voltage, the device will reduce the amount of current flowing and the output voltage will begin to decrease.Conclusion
The LT1963AET-1.8#30PBF is a highly efficient voltage regulator device with low quiescent current, high accuracy and low noise. It is suitable for a wide range of applications including portable and desktop notebooks, PDAs, digital cameras, and LCD TVs. The device can be used to provide regulated voltage for systems that require low noise, low power consumption and high efficiency. The device features a typical dropout voltage of 300mV, meaning that when supplying an output voltage of 5V, the minimum input voltage will be 5.3V. The device also features a 3-terminal fixed output voltage of 1.8V with an accuracy of ±2% and an adjustable voltage range of 1.22V to 20V. It has a TO-263 package and requires a minimum footprint size of only 3mm2, and the device supports low output voltage slew rates of up to 0.3V/µs.The specific data is subject to PDF, and the above content is for reference
