The ET5907 is a high-performance LDO linear regulator designed for demanding applications requiring high current and low dropout. It delivers a fixed 3.7V output with a maximum current of 1.2A. The device features an exceptionally low dropout voltage of 0.1V at 1A, making it highly efficient for battery-powered systems. With a PSRR of 80dB at 1kHz, it effectively filters power supply noise, ensuring clean power for sensitive analog and RF circuits. The compact 20-WLCSP package is ideal for space-constrained designs.
- Exceptional Efficiency: Ultra-low 0.1V dropout at 1A reduces power dissipation and extends battery life.
- High Noise Rejection: 80dB PSRR at 1kHz provides a clean output for sensitive RF and audio circuits.
- High Current Capability: 1.2A output supports power-hungry loads like processors and RF modules.
- Ultra-Compact WLCSP: The 1.68x2.08mm package is ideal for miniaturized portable devices.
High-Efficiency Power Conversion
With a dropout of only 0.1V at 1A, the ET5907 is perfect for converting a 3.8V battery rail to a stable 3.7V with minimal power loss.
RF and Wireless Modules
The 80dB PSRR at 1kHz ensures clean power for RF transceivers, reducing spurious emissions and improving signal integrity.
Processor Core Supplies
Capable of sourcing 1.2A, it can power low-voltage application processors or FPGAs that require a tight 3.7V rail.
Portable Audio Equipment
High PSRR minimizes audible noise from power supply ripple, enhancing audio fidelity in DACs and amplifiers.
Optical Modules
The ultra-low dropout and high current capability make it suitable for powering laser drivers in SFP+ transceivers.
Battery Management Systems
Its low dropout allows efficient regulation from a nearly depleted Li-ion cell, maximizing usable capacity.
