The LT3015ET-12 is a 1.5A low dropout linear regulator providing a fixed -12V output. It features a low dropout voltage of 0.68V at full load, enabling efficient operation from input supplies as low as -12.68V. With a quiescent current of only 2.4mA, it is well-suited for battery-powered and always-on applications. The TO-220-5 package ensures excellent thermal performance for demanding industrial and audio applications.
- High Current Capacity: Delivers up to 1.5A, suitable for powering multiple loads or high-current circuits.
- Low Dropout Voltage: 0.68V at 1.5A allows operation with minimal headroom, improving efficiency.
- Excellent PSRR: 53dB at 120Hz rejects power supply noise, critical for audio and precision analog circuits.
- Low Quiescent Current: 2.4mA reduces power consumption in standby and battery-operated systems.
Precision Negative Rail for Op-Amps
Use the LT3015ET-12 to create a clean -12V rail for high-precision operational amplifiers in audio or instrumentation circuits. Its low dropout of 0.68V ensures stable operation even with marginal input supply margins.
Industrial Sensor Power
Power industrial sensors requiring a stable -12V supply. The 1.5A current capability supports multiple sensors, while the 53dB PSRR at 120Hz rejects mains-related noise from the input supply.
Bipolar ADC Reference Supply
Generate a low-noise negative reference for bipolar analog-to-digital converters. The low quiescent current (2.4mA) minimizes power dissipation in always-on applications.
Audio Equipment Negative Rail
Supply the negative rail for audio preamplifiers and mixers. The low dropout and high PSRR help maintain audio signal integrity by reducing power supply induced hum.
Test & Measurement Equipment
Provide a stable -12V output for benchtop instruments. The TO-220 package with exposed pad allows efficient heat dissipation for continuous 1.5A operation.
Automotive Negative Supply
Generate a regulated -12V from a -14V battery rail in automotive test systems. The robust design handles load transients while maintaining output accuracy.
