DC832A - LT3028DHC Demo Board | Dual Input, Dual Output Linear Regulator, 2.3V ≤ VIN ≤ 20V, Vout1 = 2.5V/3.3V/5V @ 500mA, Vout2 = 2.5V/3.3V/5V @ 100mA
Demonstration circuit 832 is a dual output, dual input regulator consisting of two LDO linear regulators, based on the LT3028 monolithic linear regulator in the 5x3 DFN-16 package. Each independent input has a voltage range of 2.3V to 20V, with one output (Vout1) capable of delivering up to 500mA of output current, and the other output (Vout2) capable of delivering up to 100mA of output current. The two output voltages are set independently with jumpers; eachcan be set to 2.5V, 3.3V, 5V or a user-defined value (two jumper options for this).
The DC quiescent current is typically only 50uA (for the entire IC) at no load.
