The LT1764EFE#TRPBF is a high-performance, 3A low dropout linear regulator from Analog Devices. It offers an adjustable output from 1.21V to 20V, with a low dropout voltage of just 0.45V at full load. Its 1.5mA quiescent current and 63dB PSRR at 120Hz make it an excellent choice for noise-sensitive and battery-powered applications. Housed in a thermally efficient 16-TSSOP-EP package, it provides a compact, reliable power solution for demanding industrial, automotive, and communications systems.
- High Current Capacity: Delivers up to 3A, suitable for powering modern processors and FPGAs that require substantial current.
- Low Dropout Voltage: 0.45V dropout at 3A maximizes efficiency and allows operation with minimal input-to-output voltage difference.
- Excellent Ripple Rejection: 63dB PSRR at 120Hz ensures a clean output, effectively filtering supply noise from switching regulators.
- Adjustable Output Flexibility: Output voltage set from 1.21V to 20V with external resistors, accommodating a wide range of design requirements.
High-Current FPGA and DSP Core Supplies
The LT1764EFE#TRPBF delivers up to 3A with a dropout of only 0.45V, making it ideal for powering the core voltages of FPGAs and DSPs that require tight regulation and high current from a 2.5V or 3.3V rail.
Post-Regulation for Switching Converters
With 63dB PSRR at 120Hz, this LDO effectively attenuates ripple and noise from a preceding DC-DC converter, providing a clean, low-noise supply for sensitive analog and RF circuitry.
Battery-Powered Portable Instruments
The 1.5mA quiescent current and low dropout allow the regulator to extract maximum usable capacity from Li-Ion or multi-cell battery packs while maintaining a stable output as the battery voltage decays.
Precision Analog and Data Converter Supplies
Its low output noise and high PSRR make it suitable for powering precision op-amps, ADCs, and DACs, where supply noise directly impacts signal integrity and conversion accuracy.
Automotive Infotainment and Telematics
The wide input range and robust thermal package (TSSOP-EP) support operation in automotive environments, powering infotainment processors and communication modules from a 12V battery bus.
Industrial Sensor and Actuator Power
For industrial control systems, the LT1764EFE provides a stable, low-noise rail for sensor signal conditioning and actuator drivers, ensuring reliable operation in noisy factory floor environments.
