LT3042 Dual Positive Voltage Low Noise High Precision Linear Regulator DC Power Supply For DAC
Description:
- This product uses the official recommended method of Linear Technology LT high-end linear regulator chip LT3042 + PNP current expansion, can provide a DC regulated power supply close to 0 noise, and can output a high current of 1.5A. Can be used for high-precision measurement instruments, noise sensitive RF applications power supply , DAC audio decoder and other equipment to provide a pure power supply, noise as low as 1uV noise voltage, than LM317 LM78XX and other regulator noise is 2-3 levels lower, the effect is very good, you can make audio equipment to achieve background black.
- Input methods are DC and AC 2 ways, 2 groups of positive voltage independent output, such as output 1 group 5V , 1 group 3V2 or output 2 groups 3V3 Note the voltage needed when shooting.
Features
- Low RMS noise: 0.8μVRMS (10Hz to 100kHz)
- Low Point Noise: 2nV/√Hz (at 10kHz)
- High PSRR: 79dB (at 1MHz)
