LT3042 1.5A Low Noise High Precision Linear Regulated Dual DC Power Supply Module
For DAC Audio Decoder RF Power Amplifier
Description:
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-precision measuring instruments, noise-sensitive RF applications, and DAC 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.
There are two input modes: DC or AC, and Two group of positive voltage independent outputs (Default output DCOUT1=5V DCOUT2=5V).
Features:
Low RMS Noise: 0.8μVRMS (10Hz to 100KHz)
Low Point Noise: 2nV/√Hz (at 10KHz)
High PSRR: 79dB (at 1MHz)
Single Capacitor Improves Noise and PSRR
100μA SET Pin Current: ±1% initial accuracy
High Bandwidth: 1MHz
Low Dropout Voltage: 350mV
Output Voltage Range: 0V to 15V
Quick Start capability
High Precision Enable / UVLO
Multiple devices can be paralleled to reduce noise and provide higher current
Internal Current Limit with Foldback
