Analog Devices Inc. EVAL-LT3078 Evaluation Board

Analog Devices Inc. EVAL-LT3078 Evaluation Board evaluates the LT3078 Linear Regulator. The LT3078 is a 5A, ultra-low noise, high power-supply rejection ratio (PSRR), 55mV dropout ultra-fast linear regulator. The evaluation board has a 0.6V to 5.5V input voltage (VIN) range for the VIN power and a 5A maximum output current. There are jumpers to set a 3-bit trilevel code determining the output voltage (VOUT) at preprogrammed levels ranging from 0.5V to 4.2V. EVAL-LT3078-AZ requires an external BIAS voltage (VBIAS) that is at least 1.2V higher than VOUT and is between 2.375V and 5.5V.

Features
