Its application field includes automotive, portable and industrial power supplies, battery-powered applications, medical and healthcare equipment, broadcast, telecommunications and server systems. LT1965EDD#PBF are particularly effective in small, power-sensitive applications that require long battery life and stability over wide temperature ranges.

LT1965EDD#PBF Working Principle

The LT1965EDD#PBF Linear Regulator has a basic three terminal configuration, composed of an input voltage terminal, an output voltage terminal, and a ground terminal. The input voltage is applied to the input terminal, and an equal amount is applied to a series pass transistor. The magnitude of the voltage fed to the output terminal is the sum of the input voltage and the voltage drop across the pass transistor. This passes an amount of current from the input side to the output side, enough to meet the current requirements at the output terminal.

The voltage regulator also contains a reference voltage source. This is fed to an error amplifier, which compares the output voltage to the reference voltage. The error amplifier amplifies this difference, and the output is fed back to the pass transistor, modulating the current that passes through it. This feedback loop ensures that the output voltage is regulated.

Features and Advantages

LT1965EDD#PBF offer outstanding performance and reliability, and they are designed to ensure superior reliability in hot or cold temperature conditions. Features include low quiescent current, wide input voltage range, temperature range from -40°C to +125°C, and high current capability.
