LDOVR TPS7A4700/3301
Dual Ultra Low Noise Regulated Linear Power Supply -3V to -18V / +1.4V to +20.5V 1A
This TPS7A4700/3301 dual LDOVR regulated linear power supply module provides extremely low noise levels measured at only 4µvrms for the positive rail and 16µVrms for the negative rail. Its input voltage range is from 3 to 25VDC or 3 to 18VAC. Its outputs are adjustable from 1.4V to 20.5V 1A in 0.1V steps for the positive rail and from -3V to -18V in 1V steps for the negative rail, using solder pads on the PCB :
