The ET553ADJYB is an adjustable LDO from ETEK Microelectronics, delivering up to 500mA. Its output can be set via external resistors, with a typical 3.6V configuration. The 4-DFN package (1.2x1.2mm) is compact, and 85µA quiescent current balances performance and efficiency.
- Adjustable Output: Flexible voltage setting from 1V to 3.6V+ via resistors.
- High Current: 500mA supports power-hungry loads.
- Excellent PSRR: 80dB at 1kHz for clean analog supplies.
- Compact DFN: 1.2x1.2mm package saves space.
FPGA Core Supplies
Adjustable output allows precise setting of 1.8V or 2.5V cores, with 500mA capacity for small FPGAs.
Portable Audio DACs
80dB PSRR at 1kHz ensures clean analog supply, reducing audio distortion in high-end players.
