DC2637A

DC2637A is a LT3045EDD-1 20V, 2A, paralleled ultra-low noise, ultra-high PSRR LDO regulator demonstration board. Demo circuit 2637A features four LT®3045EDD-1s in parallel, generating an ultralow noise, ultrahigh power supply rejection ratio (PSRR) low dropout (LDO) regulator with programmable current limit. DC2637A operates over an input range of 3.8V to 20V and is capable of delivering up to 2A output current by paralleling four LT3045EDD-1s with only 20mohm ballast resistors. The VIOC tracking function of the LT3045EDD-1 controls an upstream switching converter to maintain a constant voltage across the regulator and hence minimize power dissipation. Built-in protection includes reverse battery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis.
