The Texas Instruments LP38690SD-2.5 is a fixed 2.5V output LDO linear regulator rated for 1A. With a dropout of 1.3V at full load and 55 μA quiescent current, it balances performance and efficiency. The 6-WSON (3x3) package offers excellent thermal performance for compact designs. Its 55dB PSRR at 120Hz ensures clean power for sensitive analog and digital circuits.
- High Current Density: 1A output in a small 3x3mm WSON package saves board space.
- Stable Output: 55dB PSRR at 120Hz rejects line-frequency noise for reliable operation.
- Low Dropout: 1.3V dropout at 1A enables efficient conversion from 3.8V rails.
- Thermal Efficiency: Exposed pad design improves heat transfer to the PCB.
FPGA Core Power
The 1A output and 2.5V rail are well-suited for low-power FPGA core supplies, where tight voltage regulation is critical for logic stability.
DSP and Processor I/O
Provides a clean 2.5V supply for DSP I/O banks and memory interfaces, with 55dB PSRR at 120Hz to reject mains hum.
Industrial Control Systems
The 6-WSON package with exposed pad aids heat dissipation in 24V industrial backplanes, stepping down to a stable 2.5V logic rail.
Networking Equipment
Powers PHY transceivers and switch ASICs requiring 2.5V, with 1A headroom for transient loads during packet bursts.
Test and Measurement
Low dropout of 1.3V at 1A allows operation from a 3.8V rail, enabling precise 2.5V references for ADC/DAC circuits.
Consumer Audio DACs
Delivers a quiet 2.5V analog supply, reducing noise floor in high-resolution audio players.
