The LT3015IDD-15 is a 1.5A low dropout linear regulator delivering a fixed -15V output. Its low dropout voltage of 0.5V at full load enables efficient operation from input supplies as low as -15.5V. The quiescent current of 2.4mA makes it suitable for battery-powered applications. The compact 8-DFN (3x3) package is ideal for space-constrained designs requiring high performance.
- Compact DFN Package: 8-DFN (3x3) saves PCB space while providing excellent thermal performance.
- Low Dropout: 0.5V at 1.5A maximizes efficiency and allows lower input voltage operation.
- High Output Current: 1.5A capability supports demanding loads.
- Low Quiescent Current: 2.4mA ideal for battery-operated equipment.
Compact Negative Rail for Portable Instruments
