Linear voltage regulators, often referred to as linear voltage regulators, are essential components in many types of electronic systems. They are used to provide a stable output voltage for use in a variety of circuits and systems, such as voltage regulators, power supplies and power amplifiers. LT3007ETS8-1.8#TRPBF is one of these types of devices, featuring excellent performance, low cost and wide range of applications.

Application Field

The LT3007ETS8-1.8#TRPBF is a low-noise, low-dropout regulator (LDO) that combines high performance with very low quiescent current. It provides 2A of output current with a dropout voltage of less than 1.5V and a minimum quiescent current of 1µA. It features a wide input voltage range of 1.8V to 25V. With its low operating current, low noise and low cost, the LT3007ETS8-1.8#TRPBF is an ideal choice for a variety of applications. These include portable electronics and PCs, battery-powered systems, power amplifiers, and a wide range of consumer electronics.

It also features a ripple rejection of 66.5dB at 10kHz, very low noise and an excellent output voltage accuracy of ±1%. This makes it ideal for applications that require ultra-low power and noise, such as medical electronics and environments where extremely low-noise or low-power operations are required.

Working Principle

The LT3007ETS8-1.8#TRPBF is an N-channel, low-dropout linear regulator. It works by providing a constant voltage from an unregulated supply source to an output load, regardless of input voltage fluctuations or variations in load current. A key element of its design is the series pass transistor, which senses the output voltage and adjusts its output as required to keep the output voltage at the set voltage level.

The device is enabled by a voltage applied to the EN pin on the device, which can be controlled externally. When the enable pin is high, the output voltage follows the input voltage of the VIN pin. When the enable pin is low, the device turns off the output voltage and the output voltage is held in a constant voltage state, regardless of the voltage fluctuations at the input. This makes the device ideal for battery-powered systems, as it will provide a constant voltage even if the battery voltage drops.

The device also includes a temperature protection circuit, which limits the maximum junction temperature of the device, protecting it from thermal overload. The device also has a built-in soft start feature, which allows the output voltage to be ramped up gradually to minimize output voltage overshoot and minimize the inrush current due to the load. With its adjustable current limit and thermal protection, the LT3007ETS8-1.8#TRPBF is a very reliable and versatile linear voltage regulator.
