The LT3065HDD#PBF from Analog Devices is a high-performance, 500mA low dropout linear regulator. It offers an adjustable output from 0.6V to 40V, making it exceptionally versatile. With an ultra-low quiescent current of just 110µA and excellent 85dB PSRR, it delivers clean, stable power for noise-sensitive and battery-powered applications. Its low 0.51V dropout voltage ensures efficient operation even with tight input-to-output margins, all in a compact 3x3mm DFN package.
- Extended Battery Life: The ultra-low 110µA quiescent current minimizes standby power draw, significantly extending runtime in portable devices.
- Clean Power Delivery: With 85dB PSRR at 120Hz, it effectively filters input ripple, ensuring a stable, noise-free output for sensitive analog and RF circuits.
- Wide Design Flexibility: The adjustable output from 0.6V to 40V and wide input range support a broad spectrum of applications, from low-voltage logic to high-voltage industrial rails.
- High Efficiency in Tight Spaces: The low 0.51V dropout voltage at 500mA reduces power dissipation, allowing for smaller heatsinks and more compact designs.
Battery-Powered Instrumentation
The ultra-low 110µA quiescent current and wide 0.6V to 40V output range make it ideal for portable medical devices and field instruments where battery life is critical.
Automotive Power Supplies
With a 40V input rating and 85dB PSRR at 120Hz, this LDO provides clean, stable power for automotive ECUs and sensor interfaces, rejecting alternator ripple and load transients.
