The LT1764EFE-2.5 is a fixed 2.5V linear regulator from Analog Devices, capable of delivering 3A with a dropout voltage of only 0.45V. Its low quiescent current of 1.5mA makes it efficient for battery-powered applications. The 16-lead TSSOP-EP package provides excellent thermal performance. With PSRR of 63dB at 120Hz, it effectively suppresses power supply ripple, ensuring clean output for sensitive electronics.
- High 3A Output Current: Supports demanding loads like FPGAs and processors.
- Ultra-Low Dropout (0.45V @ 3A): Minimizes power loss and heat generation.
- Low Quiescent Current (1.5mA): Extends battery life in portable devices.
- High PSRR (63dB @ 120Hz): Provides clean power for noise-sensitive circuits.
High-Current 2.5V Rails for FPGAs and DSPs
The 3A output with 0.45V dropout ensures stable 2.5V power for core logic, even when input rails sag under load.
Post-Regulation for Switching Converters
With PSRR of 63dB at 120Hz, it effectively cleans ripple from a buck converter, providing low-noise 2.5V for analog circuits.
Battery-Powered Industrial Equipment
Low quiescent current (1.5mA) extends standby time, while the 3A capability supports high-current bursts in motors or actuators.
Server and Telecom Power Distribution
The TSSOP-EP package dissipates heat efficiently, making it suitable for 2.5V I/O rails in networking equipment.
Automotive Infotainment Processors
Fixed 2.5V output simplifies design, and the low dropout ensures operation during cold-crank conditions.
Precision Reference Supplies
The low noise and high PSRR make it ideal for powering precision ADCs and DACs requiring a clean 2.5V reference.
