EVAL-LT3073-AZ

EVAL-LT3073-AZ evaluation board features the LT3073, a 3A, ultra-low noise, high power-supply rejection ratio (PSRR), 45mV dropout ultra-fast linear regulator. The input voltage (VIN) range for the VIN power is from 0.6V to 5.5V. There are jumpers to set a 3-bit trilevel code that determines the output voltage (VOUT) at preprogrammed levels that range from 0.5V to 4.2V. The maximum output current is 3A. The EVAL-LT3073-AZ requires an external BIAS voltage (VBIAS) that is at least 1.2V higher than VOUT and is between 2.375V and 5.5V. The LT3073 of the EVAL-LT3073-AZ requires few external components; therefore, simplifying circuit design. External component choice along with careful PCB design help optimize noise, PSRR, load transient response, and VOUT regulation performance. The LT3073 requires capacitors for the internal reference, power input, BIASF pin, and the power output.

• Jumper, resistor combinations select either 3.72/1.5A output current limit & commensurate monitoring
• Jumper turns regulator on or off
• Terminals provide output current, temperature, and output regulation status monitoring
• Jumper to margin output voltage ±2.5%
• The VIOC pin of the LT3073 manages power dissipation and PSRR
• Banana jacks minimize VIN and VOUT connection voltage drops
• VO+, VO−, and VI+ terminals for regulation and dropout monitoring
• Thermally enhanced, 22-lead, 3 mm × 4 mm x 0.95 mm, LQFN package
