The LP3991TLX-1.7 is a low dropout linear regulator providing a fixed 1.7V output at up to 300mA. With an ultra-low dropout of 0.16V and quiescent current of 100 µA, it is designed for battery-powered, space-constrained applications. The 4-DSBGA package is among the smallest available.
- Ultra-low dropout (0.16V @ 300mA) maximizes efficiency.
- Very small 4-DSBGA (1x1) package for miniaturized designs.
- Low quiescent current (100 µA) extends battery life.
- High PSRR (65dB @ 1kHz) ensures clean output.
Low-Voltage Digital Cores
1.7V output and 300mA support low-power MCUs and memory in portable devices.
Battery-Powered Medical Devices
Low dropout (0.16V) maximizes battery utilization in glucose meters and hearing aids.
Wireless Sensor Nodes
100 µA quiescent current and tiny DSBGA package suit energy-harvesting applications.
Smartphone Peripherals
Provides clean 1.7V rail for camera sensors and display drivers.
Portable Audio Players
PSRR of 65dB at 1kHz reduces power supply noise for audio quality.
