The ETEK ET553ADJY2B is an adjustable LDO linear regulator capable of delivering 500mA. It features a typical output of 3.6V (set by external resistors) and a dropout of 0.9V at full load. The quiescent current is 85 µA. Housed in a 6-DFN (2x2mm) package, it offers high PSRR (80dB at 1kHz) for clean power in adjustable supply applications.
- Adjustable Output: Flexible voltage setting via external resistors.
- High Current: 500mA for power-hungry loads.
- High PSRR: 80dB at 1kHz for noise-sensitive circuits.
- Wide Input Range: Operates from 1V, suitable for low-voltage sources.
