We have started offering a pin compatible alternative to the LM78XX series of linear voltage regulators. The VR78XX is a low dropout, ultra low-noise (4 uV RMS) linear voltage regulator designed around the TPS7A4700 regulator chip which is capable of sourcing a 1 amp load.
We chose the TPS7A4700 for some upcoming new products as well as a replacement regulator for our existing passive preamp product line. Since we'll be using these we came up with a small VR78XX module that we're also making available to the DIY community.
Aside from being a highly accurate and low noise regulator it can be programmed (via soldered jumpers) to output from 1.4 VDC plus any combination of 0.1V, 0.2V, 0.4V, 0.8V, 1.6V, 3.2V, 6.4V, & 6.4V for a max total output of 20.6 VDC.
This pic below is from CAD drawings. Will post pics of actual module soon but the cad pics are quite accurate except the one shows all the pads populated with surface mount components whereas only 3 capacitors plus the main regulator chip are installed. The other pads are for the voltage programming.
Pricing is $25 for single units, less for quantity which includes free 1st class shipping within US. More info here:
