The LT1764AET#30PBF is a high-performance low dropout linear regulator from Analog Devices, delivering a fixed 20V output at up to 3A. With a low dropout voltage of just 0.66V and a quiescent current of 1.5 mA, it offers excellent efficiency for high-current applications. Its 63dB PSRR at 120Hz ensures clean, noise-free power for sensitive electronics. Housed in a robust TO-220-5 package, it is ideal for industrial, audio, and test equipment requiring reliable voltage regulation.
- High Output Current: Delivers up to 3A, making it suitable for powering demanding digital and RF loads without voltage sag.
- Low Dropout Voltage: The 0.66V dropout at full load allows operation from marginally higher input supplies, reducing power dissipation and improving efficiency.
- Excellent Ripple Rejection: With 63dB PSRR at 120Hz, it effectively filters out power supply noise, ensuring clean output for precision analog circuits.
- Low Quiescent Current: The 1.5 mA quiescent current helps extend battery life in portable and standby applications.
High-Current 20V Rail Generation
Use the LT1764AET#30PBF to create a stable 20V rail from a higher unregulated supply. Its 3A current capability supports power-hungry loads like FPGAs, ASICs, and RF power amplifiers that require a clean, low-noise 20V supply.
Post-Regulation for Switching Converters
Place this LDO after a DC-DC converter to attenuate switching ripple and noise. With 63dB PSRR at 120Hz, it effectively cleans up the output, providing a low-noise analog supply for precision instrumentation and audio circuits.
Battery-Powered Equipment
The low 1.5 mA quiescent current extends battery life in portable devices. Its low dropout of 0.66V allows operation even as the battery voltage depletes, maximizing usable battery capacity.
