DC1938A

Demonstration circuit 1938A features the LT3072 dual, low noise, 2.5A programmable output, low dropout linear regulator. The input voltages VIN1 and VIN2 are independent and can range from 0.8V to 3.45V. Each channel has jumpers to set a three-bit code that determines output voltages VOUT1 and VOUT2 at pre-programmed levels with a range from 0.6V to 2.5V and a maximum output current of 2.5A. DC1938A requires a single external BIAS voltage that is higher than VIN1 and VIN2, between 2.375V and 5.25V and is at least 1.2V higher than the highest output voltage.
