The Texas Instruments LP5990TMX-1.8/NOPB is a fixed 1.8V low dropout linear regulator capable of delivering 200mA. Its low 75 µA quiescent current and 0.25V dropout at full load make it suitable for battery-powered and portable applications. The 4-DSBGA package minimizes board space, while 55dB PSRR at 10kHz ensures stable, low-noise output for sensitive electronics.
- Extended Battery Life: Ultra-low 75 µA quiescent current reduces standby power consumption in portable devices.
- Compact Footprint: 4-DSBGA package saves critical PCB area for miniaturized designs.
- Stable Output: 55dB PSRR at 10kHz filters supply noise for clean power delivery.
- Low Dropout: 0.25V dropout at 200mA maximizes efficiency by allowing operation close to the output voltage.
Portable Battery-Powered Devices
The 1.8V output and low 75 µA quiescent current make it ideal for extending battery life in wearables, IoT sensors, and handheld instruments where standby power is critical.
RF and Analog Supply Rails
With 55dB PSRR at 10kHz, this LDO effectively filters high-frequency noise, providing a clean supply for RF transceivers, PLLs, and precision analog circuits.
Microcontroller Core Power
Modern MCUs often require a stable 1.8V core supply. The LP5990TMX-1.8 delivers up to 200mA with tight regulation, ensuring reliable operation during active processing.
Space-Constrained Designs
The ultra-small 4-DSBGA package (approximately 1x1mm) fits into compact PCBs for smart earbuds, medical patches, and miniature sensor modules.
Noise-Sensitive Audio Codecs
Its PSRR performance helps prevent power supply-induced artifacts in audio codecs and DACs, maintaining signal integrity in portable audio equipment.
Always-On Domains
The low quiescent current supports always-on memory and wake-up circuits in battery-operated systems, minimizing drain during sleep modes.
