The Analog Devices MAX8559ETA22+T is a dual-output LDO linear regulator providing two fixed 1.8V rails, each capable of sourcing 300mA. It features a low quiescent current of 290 µA and excellent PSRR (70dB at 10kHz), ensuring clean and stable power for noise-sensitive applications. The compact 8-TDFN (3x3) package is perfect for space-constrained designs requiring multiple regulated voltages.
- Dual 1.8V Outputs: Powers multiple subsystems with independent, regulated rails from a single component.
- High Output Current per Channel (300mA): Supports a wide range of digital and analog loads.
- Excellent PSRR (70dB @ 10kHz): Provides superior noise filtering for RF and precision analog circuits.
- Compact 8-TDFN Package: Ideal for space-limited portable and wearable devices.
Dual-Supply Microcontrollers
Many modern MCUs require separate 1.8V supplies for core and I/O. The MAX8559ETA22+T provides two regulated 1.8V outputs from a single package, simplifying power distribution and saving board space.
Portable Consumer Electronics
In smartphones and tablets, this dual LDO can power different sections like memory and logic, each requiring a clean 1.8V rail, while the low quiescent current helps conserve battery power.
RF Transceiver Modules
The high PSRR (70dB at 10kHz) ensures that noise from the power supply does not interfere with sensitive RF components, maintaining signal clarity in wireless modules.
Sensor Arrays
For systems with multiple digital sensors operating at 1.8V, this dual regulator provides independent, low-noise power rails, preventing cross-talk and ensuring accurate sensor readings.
Networking and Communication
In networking equipment, the MAX8559ETA22+T can power low-voltage logic and interface circuits, offering a compact and efficient solution for dual-rail requirements.
Wearable Devices
The small 8-TDFN package and dual outputs make it ideal for wearables, where space is at a premium and multiple low-voltage rails are needed for different subsystems.
