The LT3091EDE is a high-performance negative linear regulator from Analog Devices, capable of delivering up to 1.5A with an output voltage range down to -32V. Its ultra-low quiescent current of 50.5µA and excellent PSRR make it a superior choice for noise-sensitive applications. The 14-DFN package offers a compact solution for space-constrained designs.
- Ultra-Low Quiescent Current: 50.5µA quiescent current minimizes power loss, ideal for battery-operated devices.
- High PSRR: 85dB at 120Hz and 20dB at 1MHz ensures clean output, reducing noise in sensitive analog circuits.
- Low Dropout Voltage: 0.45V at 1.5A allows operation with minimal headroom, improving efficiency.
- Wide Output Range: Adjustable down to -32V provides flexibility for various negative rail requirements.
Precision Negative Power Supplies
The LT3091EDE's low quiescent current and high PSRR (85dB at 120Hz) make it ideal for precision analog circuits requiring a clean negative rail, such as operational amplifiers and data converters.
Battery-Powered Instrumentation
With a quiescent current of only 50.5µA, this regulator extends battery life in portable devices while providing a stable -32V output for sensors and transducers.
Low-Noise Audio Circuits
The high PSRR across a wide frequency range (85dB to 20dB from 120Hz to 1MHz) ensures minimal power supply noise in audio preamplifiers and DACs.
Industrial Sensor Interfaces
The 1.5A output current capability and low dropout voltage (0.45V) allow for efficient power delivery in industrial control systems with varying input voltages.
Post-Regulation for Switching Converters
Use the LT3091EDE after a negative DC-DC converter to reduce ripple and noise, achieving a clean output for sensitive RF and mixed-signal applications.
