The LT1761ES5-2.8#TRMPBF is a high-performance, low dropout (LDO) voltage regulator from Linear Technology, designed to deliver a continuous output of 2.8 volts. This component is part of the LT1761 series, which is known for its low noise and excellent power supply rejection ratio (PSRR), making it an ideal choice for sensitive RF and analog circuitry that requires a clean and stable power supply.

With the ability to supply up to 100mA of output current, this voltage regulator maintains a low dropout voltage of just 300mV at full load, which enhances the efficiency of the system by allowing operation close to the input voltage. The LT1761ES5-2.8#TRMPBF is particularly suitable for battery-powered devices, as it extends battery life through its low quiescent current of 20μA in operation and less than 1μA in shutdown mode.

The device features multiple layers of protection, including over-current and over-temperature protection, ensuring reliable operation under various conditions. It also has the capability to start up with capacitive loads up to 10μF, making it versatile for different design requirements.

One of the standout features of the LT1761 series is its low noise output, which is critical for RF and precision analog applications. The LT1761ES5-2.8#TRMPBF achieves this with its low noise of only 20μV RMS across a 10Hz to 100kHz bandwidth without the need for an additional noise bypass capacitor.

This voltage regulator comes in a compact SOT-23 package, which is ideal for space-constrained applications. The LT1761ES5-2.8#TRMPBF is also characterized for operation from -40°C to 125°C, covering a wide range of temperature conditions, making it suitable for industrial and automotive applications as well.

With its combination of low dropout performance, low noise characteristics, and robust protection features, the LT1761ES5-2.8#TRMPBF from Linear Technology is an excellent choice for designers looking to optimize their power management solutions in sensitive and compact electronic systems.
