What are the key features of LT1764EFE-3.3#PBF?
- Fixed 3.3 V output LDO with 3 A current capability and only 340 mV nominal dropout for efficient regulation from 4 V to 20 V input rails
- Fast transient response and low output noise optimized for DSP, FPGA, and processor core supply rails sensitive to voltage glitches
- 16-pin TSSOP-EP (R-PDSO-G16) package with exposed pad for enhanced thermal dissipation supporting 3 A continuous output without external heatsink
What is LT1764EFE-3.3#PBF used for?
The LT1764EFE-3.3#PBF supplies stable 3.3 V rails to FPGAs, DSPs, and microprocessors where fast load-transient response and low output noise are critical for maintaining timing margins and minimizing jitter in high-speed digital designs. Its 3 A output current and 340 mV dropout support point-of-load regulation directly from a 5 V system bus or 3.6 V lithium battery. The 16-pin TSSOP-EP footprint integrates efficiently into compact PCBs for test equipment, software-defined radio platforms, and communications infrastructure line cards.

Frequently Asked Questions
What output voltage, current, and dropout does the LT1764EFE-3.3#PBF provide for digital core power supply designs?
The LT1764EFE-3.3#PBF delivers a fixed 3.3 V output at up to 3 A with a nominal dropout voltage of 340 mV and maximum of 660 mV. This allows regulation from input rails as low as 3.64 V nominal, making it suitable for powering 3.3 V digital logic, memory, and I/O banks directly from a 5 V system bus or a partially discharged 4.2 V lithium-ion cell.
How does the fast transient response of the LT1764EFE-3.3#PBF benefit FPGA and DSP power supply designs?
FPGAs and DSPs draw sudden current surges of 500 mA to 2 A within nanoseconds during clock edges and computation bursts. The LT1764's fast transient response limits the resulting output voltage undershoot to just a few millivolts per ampere of load step, preventing setup or hold violations in DDR memory interfaces and high-speed serial transceivers. This performance eliminates the need for large arrays of bulk bypass capacitors that would otherwise be required with slower LDOs.
When is the LT1764EFE-3.3#PBF a better choice than a switching regulator for a 3.3 V / 3 A supply?
For noise-sensitive analog and RF subsystems co-located on the same board as a 3.3 V digital domain, the LT1764 eliminates the switching noise, EMI, and complex filter design associated with a buck converter operating at hundreds of kilohertz. When the input rail is 5 V and the load is 2 A, the power dissipation in the LT1764 is approximately (5 V - 3.3 V) × 2 A = 3.4 W, which the 16-pin TSSOP-EP can handle with modest PCB copper area, making the linear approach simpler and quieter for applications such as ADC reference rails and RF transceiver supply domains.
