The LT3065EDD-3.3#TRPBF from Analog Devices is a high-performance fixed 3.3V LDO. It delivers 500mA with a dropout of only 0.51V and an ultra-low quiescent current of 110µA. With a wide input range up to 45V and excellent PSRR (71dB at 120Hz), it is engineered for demanding industrial and automotive environments.
- Wide Input Voltage Range: Operates from 3.81V to 45V, making it versatile for automotive and industrial rails.
- Ultra-Low Quiescent Current: 110µA reduces standby power, critical for battery-powered remote systems.
- Excellent PSRR: 71dB at 120Hz filters out line-frequency noise, ensuring clean analog supplies.
- Compact DFN Package: 10-DFN (3x3mm) saves space while providing good thermal dissipation.
Automotive ECU Power Supplies
With an input range up to 45V, this LDO can directly regulate from automotive battery lines (12V/24V) to a stable 3.3V for microcontrollers.
Industrial Process Control
High PSRR (71dB at 120Hz) rejects mains hum and industrial noise, providing clean power for PLCs and sensor transmitters.
Avionics Systems
The wide input range and low dropout make it suitable for 28V aircraft buses, delivering a regulated 3.3V rail for flight instruments.
Battery-Powered Field Instruments
110µA quiescent current extends battery life in remote monitoring equipment that operates for years on a single battery.
Telecom Base Stations
Provides a stable 3.3V rail for DSPs and FPGAs in base station controllers, with excellent noise rejection from switching supplies.
Precision Data Acquisition
The low noise and high PSRR make it ideal for powering high-resolution ADCs and DACs in test and measurement equipment.
