The ET55111YB from ETEK MICROELECTRONICS is a high-current fixed 1.1V low dropout regulator, capable of delivering 800mA. With a dropout voltage of just 0.3V at full load and a quiescent current of 110 µA, it offers excellent efficiency for high-performance applications. The ultra-small 4-DFN (1.2x1.2) package is perfect for space-constrained designs, while 80dB PSRR at 1kHz ensures clean power for sensitive digital circuits.
- High Current: 800mA output supports demanding FPGA and processor cores.
- Excellent PSRR: 80dB at 1kHz minimizes noise for high-speed digital logic.
- Low Dropout: 0.3V dropout at 800mA improves power efficiency.
- Miniature Package: 4-DFN (1.2x1.2) saves critical board space.
High-Current FPGA Cores
The ET55111's 800mA output and 1.1V rail are ideal for powering modern FPGA core logic, which requires high current at low voltages for high-speed processing.
DDR Memory Termination
For DDR3/DDR4 memory, the 1.1V output can serve as a VTT supply, with 800mA capability handling termination currents and 80dB PSRR at 1kHz ensuring signal integrity.
Application Processors
In smartphones and tablets, this LDO provides a stable 1.1V core supply for application processors, with low dropout of 0.3V to maximize efficiency from a 1.5V intermediate rail.
Optical Transceivers
