LT1965EQ-1.8#PBF - Low Noise, Low Dropout Regulator

The LT1965EQ-1.8#PBF is a high-performance low dropout linear regulator (LDO) from Linear Technology, designed to deliver a continuous output current of up to 1.1A with an output voltage of 1.8V. This regulator is part of the LT1965 series, known for its low noise and excellent power supply rejection ratio (PSRR), making it an ideal choice for sensitive RF and analog circuitry that require a clean power supply.

With a dropout voltage of just 300mV at full load, the LT1965EQ-1.8#PBF ensures efficient operation even when the input-to-output voltage differential is minimal. This characteristic is particularly beneficial in battery-operated devices where maximizing the use of available voltage is crucial.

One of the key features of this LDO is its low noise output, which is typically 40μVRMS over a 10Hz to 100kHz bandwidth. This low noise performance, combined with a very low quiescent current of 500μA operating and 1μA in shutdown, makes the LT1965EQ-1.8#PBF an excellent choice for portable and battery-powered applications where power efficiency and minimal interference are essential.

The device also includes several built-in protection features, such as overcurrent and over-temperature protection, ensuring reliable operation under a range of conditions. Additionally, the LT1965EQ-1.8#PBF is stable with output capacitors as low as 10μF, which allows for the use of small ceramic capacitors that save space and cost without compromising performance.

Enclosed in a thermally enhanced 5-lead DD-Pak package, the LT1965EQ-1.8#PBF is designed to handle high power levels while maintaining a compact footprint. This makes it suitable for a wide range of applications, including but not limited to, telecommunications, medical equipment, and instrumentation.

Overall, the LT1965EQ-1.8#PBF from Linear Technology is a robust and reliable LDO that offers a perfect balance of low noise performance, high current capability, and power efficiency, making it an excellent choice for designers looking for a high-quality power management solution.
