LT1764EQ-3.3#TRPBF

Application Field

The LT1764EQ-3.3#TRPBF is a high-efficiency, low-power, low-dropout linear regulator designed to regulate a low-voltage system power supply. This device is designed to produce output voltages as low as 1.2V and to support output currents up to 500mA. It features an I2C-controlled power management capability that allows the user to program the output voltage and current limit, as wells as shutdown and enable controls. This makes it ideal for powering a wide range of low-power electronics and providing a much-needed flexibility when setting up a power supply.

The LT1764EQ-3.3#TRPBF is also suitable for many applications where high efficiency and low dropout voltage are required; this makes it ideal for battery-powered systems, automotive applications, and control circuitry. It will also work in many other applications such as providing power for digital signal processors, analog circuitry, mixed-mode ASICs, and microcontrollers.

Working Principle

The LT1764EQ-3.3#TRPBF works on the linear regulator principle, where the output voltage is regulated by comparing the output voltage with a reference voltage. The reference voltage is generated internally and is set by the user using an external control voltage. The output voltage is then compared to the reference voltage, and when there is a difference, the regulator will adjust its internal switch accordingly to regulate the output voltage at the desired level.

This device features a low dropout voltage, which means that it can maintain regulation at properly low power levels. This is achieved by a very high-efficiency switching process, where the current flows through the device only when needed. This prevents unnecessary power loss, which helps to increase battery life and efficiency.

The LT1764EQ-3.3#TRPBF is also an I2C-controlled power management device, which allows for precise voltage and current limit settings, as well as shutdown and enable controls. This makes the device perfectly suited for a range of low-power applications and ensures the regulator is both robust and flexible when setting up a power supply.
