The MAX8559ETAG2+ is a dual-output LDO regulator from Analog Devices, providing fixed 3V and 1.8V outputs at 300mA each. It features a low dropout of 0.12V at 100mA and a quiescent current of 290µA. With PSRR of 70dB at 10kHz, it delivers clean power for noise-sensitive applications. The 8-TDFN (3x3mm) package offers excellent thermal performance.
- Dual Voltage Rails: 3V and 1.8V outputs in one package reduce component count and PCB space for multi-voltage designs.
- Excellent Noise Rejection: 70dB PSRR at 10kHz ensures stable, clean power for analog and RF circuits.
- Thermally Efficient Package: 8-TDFN with exposed pad improves heat dissipation, enhancing reliability in demanding applications.
- Low Quiescent Current: 290µA helps maximize battery life in portable devices.
Digital Core and I/O Power
The 3V and 1.8V outputs are perfect for powering mixed-voltage digital systems, such as FPGAs or DSPs that require separate core and I/O supplies.
Portable Audio Players
High PSRR (70dB at 10kHz) ensures clean power for audio DACs and amplifiers, reducing audible noise and distortion.
Wireless Communication Modules
Dual outputs can power both the RF transceiver (3V) and baseband processor (1.8V), maintaining stable operation during transmit bursts.
Industrial Sensor Interfaces
The 8-TDFN package with exposed pad aids thermal management in industrial environments where ambient temperatures are high.
Battery-Powered Instrumentation
Low quiescent current (290µA) extends battery life in handheld meters and data loggers, while dual outputs simplify power architecture.
Automotive ECU Auxiliary Power
Stable 3V/1.8V rails support auxiliary sensors and microcontrollers in automotive electronic control units, with dropout ensuring operation during cranking.
