The LP3985ITL-2.8/NOPB from Texas Instruments is a low dropout regulator offering a fixed 2.8V output at up to 150mA. Its ultra-low 0.1V dropout voltage and tiny 5-DSBGA package make it perfect for space-constrained, battery-powered devices. With 150 µA quiescent current and 50dB PSRR, it delivers clean, stable power for sensitive analog and RF circuits.
- Minimal Power Loss: 0.1V dropout at 150mA maximizes efficiency in low-voltage battery systems.
- Space-Saving Design: 5-DSBGA package (1.41x1.08mm) is among the smallest for LDOs, enabling miniaturized PCBs.
- Stable Output: 50dB PSRR at 1kHz ensures clean power for audio and RF applications.
- Reliable Performance: Texas Instruments' proven design ensures consistent operation across temperature ranges.
Ultra-Compact Wearables
The tiny 5-DSBGA package (1.41x1.08mm) is ideal for smart watches and fitness bands where board space is at a premium, while the 150mA output powers sensors and BLE modules.
Mobile Phone Audio
The 2.8V output and 0.1V dropout provide a stable supply for audio codecs and headphone amplifiers, ensuring consistent sound quality even as the battery voltage sags.
Bluetooth Low Energy Modules
With 150mA capability, it can handle peak currents during BLE transmission bursts, while the low dropout maintains the 2.8V rail from a 3.0V coin cell.
Portable Gaming Devices
Provides clean power to the display driver and haptic feedback circuits, with 50dB PSRR at 1kHz filtering switching noise from the main processor.
Medical Patch Sensors
The ultra-small footprint and low dropout make it suitable for disposable medical patches that require a stable 2.8V rail from a thin-film battery.
RF Transceivers
The 40dB PSRR at 10kHz helps reduce high-frequency noise that could interfere with RF signal integrity in short-range wireless links.
