Low RMS Noise: 0.8μVRMS (10Hz to 100kHz) Low point noise: 2nV/√Hz (at 10kHz) High PSRR: 79dB (at 1MHz) 100μA SET pin current: ±1% initial accuracy High bandwidth: 1MHz This product adopts the official recommendation method of Linear Technology's high-end linear voltage regulator chip LT3042+PNP expansion, which can provide a DC power supply with close to 0 noise, and can output a large current of 1.5A. It can supply power for high- measuring instruments, noise-sensitive applications, and audio decoders and other equipment. The noise is as low as 1uV, which is 2-3 levels lower than the regulated noise of LM317 LM78XX. Very good for making audio equipment reach the background pitch black. There are two input modes: DC and AC, and one group of positive voltage outputs. Please note the required voltage when . Input method: DC (DC 3.3V-DC 20V) / AC (AC 3V-AC 13V) Output current: 1.5A DC output mode: output DC output: 5v (factory default 5.0V) Color: As Shown Material: PCB Specification: 5V Package Contents: 1*module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
