The LT3065HDD-3.3 is a precision linear regulator from Analog Devices, offering a fixed 3.3V output and a 500mA current rating. It features a very low quiescent current of 110μA and a dropout voltage of just 0.51V at full load. The 10-DFN package and 71dB PSRR at 120Hz make it an excellent choice for space-constrained, noise-sensitive applications.
- Optimized for 3.3V Logic: Provides a precise, stable 3.3V rail for microcontrollers, FPGAs, and digital ICs, ensuring reliable logic levels.
- Superior Noise Rejection: The 71dB PSRR at 120Hz filters out power supply hum, making it ideal for mixed-signal and RF systems.
- Low Power Consumption: The 110μA quiescent current is a key advantage for battery-powered devices, reducing idle current draw.
- Wide Input Flexibility: Accepts inputs from 3.3V to 45V, allowing it to be used in multi-rail systems and automotive environments without additional pre-regulation.
Microcontroller Power Supply
The 3.3V rail is standard for modern MCUs. This regulator's 500mA output and low dropout ensure stable operation even when the input voltage is close to 3.81V.
Wireless IoT Modules
For LoRa, Wi-Fi, or BLE modules, the low quiescent current (110μA) is critical for sleep modes, while the 71dB PSRR at 120Hz ensures reliable RF performance by minimizing supply noise.
Industrial Control Interfaces
With a wide input range up to 45V, it can directly regulate from a 24V industrial bus, providing a clean 3.3V supply for PLC I/O controllers and communication transceivers.
Portable Instrumentation
The compact 10-DFN package and high efficiency make it suitable for handheld multimeters and calibrators, where space and battery life are paramount.
Automotive ECU Sensors
It provides a stable 3.3V reference for pressure, temperature, and position sensors in automotive ECUs, withstanding cranking voltage dips thanks to its low dropout.
Server and Telecom Logic
For auxiliary logic rails in servers, this LDO offers a low-noise solution to power management ICs and small FPGAs, improving system reliability.
