LT3042 1.5A Low Noise High Precision Linear Regulated Dual DC Power Supply Modul

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

 

Tips:

 

1> The default output setting for delivery is DCOUT1=5V DCOUT2=5V

 

2> Due to the resistance limitation, the output voltages can be 1.2V, 2.5V, 3.3V, 5V, 6.5V, 9V, 12V, 15V. (Factory default 5.0V)
