LT1764AEQ-ADJ#PBF - Low Dropout Linear Regulator

The LT1764AEQ-ADJ#PBF is a high-performance low dropout linear regulator (LDO) designed and produced by Linear Technology. This regulator is capable of supplying up to 3A of output current with a dropout voltage of just 340mV at full load. One of the key features of this device is its adjustable output voltage, which can be set from 1.21V to 20V with a simple external resistor divider, providing excellent flexibility for a wide range of applications.

With an operating voltage range from 2.7V to 20V, the LT1764AEQ-ADJ#PBF is suitable for a variety of input sources, including single-cell Li-Ion batteries to multi-cell battery stacks, and even automotive inputs without the need for additional protection diodes. This makes it an ideal solution for portable devices, networking equipment, and industrial applications where a stable and precise voltage is crucial.

The LT1764AEQ-ADJ#PBF features a low quiescent current, which is beneficial for battery-powered applications, as it helps to maximize battery life. The regulator’s fast transient response ensures stable operation even with rapid load changes, which is essential for high-performance digital circuits that have sharp, dynamic current demands.

Stability is ensured with low ESR (Equivalent Series Resistance) ceramic capacitors, offering a cost-effective solution without the need for bulky tantalum or aluminum electrolytic capacitors. This allows for a more compact power supply design. Additionally, the device includes over-temperature and over-current protection, enhancing its reliability and robustness in demanding situations.

The LT1764AEQ-ADJ#PBF is packaged in a thermally enhanced TSSOP-16 package, which aids in heat dissipation and allows for a more compact PCB layout. Its performance characteristics and packaging make it an excellent choice for engineers looking to optimize power management in space-conscious and thermally sensitive applications.

Overall, the LT1764AEQ-ADJ#PBF from Linear Technology is a versatile, reliable, and efficient LDO regulator that offers designers the flexibility and performance required for today's sophisticated electronic systems.
