The MAX4835ETT18BD2V+T from Analog Devices is a fixed 1.8V LDO regulator capable of 250mA output. Its ultra-low 0.165V dropout voltage at full load enables efficient conversion from 2.5V or 3.3V rails. The 150 μA quiescent current balances performance with power savings. Packaged in a compact 6-TDFN (3x3mm), it is ideal for space-constrained portable and industrial applications.
- Minimal Power Loss: 0.165V dropout at 250mA reduces heat generation and improves efficiency.
- Compact Footprint: 6-TDFN (3x3mm) saves PCB area for dense designs.
- High Current Density: 250mA in a tiny package suits modern IC power requirements.
- Low Noise Operation: Suitable for sensitive analog and RF circuits.
FPGA Core Power
Modern FPGAs require precise 1.8V core supplies. The MAX4835's 0.165V dropout at 250mA ensures stable operation even when input rails sag, while the 6-TDFN package minimizes board space.
DDR Memory Termination
For DDR2/DDR3 VTT rails, this LDO provides clean 1.8V with low noise, critical for memory signal integrity in servers and networking equipment.
Portable Audio Codecs
Supplying 1.8V to audio codecs and DACs, the MAX4835's low output noise preserves dynamic range and THD+N performance in smartphones and media players.
Optical Transceivers
In SFP+ modules, the 1.8V rail powers laser drivers and TIA circuits. The 250mA capability handles peak currents during burst-mode operation.
Wearable Health Monitors
With 150 μA quiescent current, this regulator powers 1.8V MCUs and sensors in fitness bands, balancing performance with battery conservation.
Industrial Sensors
For 1.8V logic in industrial pressure/temperature transmitters, the MAX4835 offers reliable regulation over -40°C to +125°C temperature ranges.
