The LT3015IDD#PBF is a high-performance negative linear regulator from Analog Devices, delivering a fixed -29.5V output at up to 1.5A. With a low dropout voltage of just 0.5V and excellent 65dB PSRR, it ensures clean, stable power for sensitive analog and mixed-signal circuits. The compact 8-DFN package is ideal for space-constrained designs.
- High Output Current: 1.5A capability supports demanding loads while maintaining regulation.
- Low Dropout Voltage: 0.5V dropout maximizes efficiency by allowing operation close to the input rail.
- Excellent PSRR: 65dB at 120Hz rejects power supply noise, critical for audio and precision instrumentation.
- Compact DFN Package: 3x3mm footprint saves board space without sacrificing thermal performance.
