The LT1764AET-1.8#30PBF is a robust 3A low dropout linear regulator from Analog Devices, offering a fixed 1.8V output. It features a low dropout voltage of 0.66V at full load, making it efficient for converting from higher voltage rails. With a quiescent current of only 1.5mA, it balances performance with power efficiency. The TO-220-5 package ensures excellent thermal performance for high-current applications. This regulator is well-suited for processor cores, post-regulation, and industrial power supplies where reliability and clean output are essential.
- High 3A Output Current: Supports demanding loads such as processor cores and ASICs.
- Low Dropout (0.66V @ 3A): Allows efficient regulation from lower input voltages, reducing power loss.
- Excellent 120Hz PSRR (63dB): Effectively filters mains hum, ideal for audio and precision analog circuits.
- Low Quiescent Current (1.5mA): Improves efficiency in battery-powered and always-on applications.
- Thermally Efficient TO-220 Package: Ensures reliable operation under high load and ambient temperatures.
High-Current Processor Cores
Modern microprocessors and FPGAs require stable 1.8V rails at up to 3A. The LT1764A's high current capability and low dropout ensure reliable operation during transient load steps.
Post-Regulation for Low-Voltage Rails
When a switching regulator provides a 2.5V rail, the LT1764A can post-regulate it down to a clean 1.8V, reducing ripple and providing a low-impedance source.
Audio and Video Equipment
With 63dB PSRR at 120Hz, this LDO effectively rejects mains-frequency hum, making it suitable for powering sensitive analog audio circuits and video processing stages.
Industrial Control Systems
The robust TO-220 package handles high power dissipation, making it ideal for industrial environments where heat is a concern and reliability is paramount.
Telecom and Networking Gear
For line cards and routers, the LT1764A provides a reliable 1.8V supply for ASICs and SerDes transceivers, ensuring signal integrity.
