EVAL-LT3078-AZ

EVAL-LT3078-AZ is an evaluation board that features LT3078, a 5A, ultra-low noise, high PSRR, 55mV dropout ultra-fast linear regulator. The input voltage (VIN) range for 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 5A. The board requires an external BIAS voltage (VBIAS) that is at least 1.2V higher than VOUT and is between 2.375V and 5.5V. The LT3078 of the EVAL-LT3078-AZ requires few external components, therefore, simplifying circuit design. External component choice with careful PCB design helps to optimize noise, PSRR, load-transient response, and VOUT regulation performance. The LT3078 requires capacitors for the internal reference, power input, BIASF pin, and power output. The internal reference is bypassed with a 16V, 0805 sized, 4.7µF capacitor to reduce output noise and program the soft-start.

• BNC connectors for noise and PSRR measurement
• Jumper turns regulator on or off
• Terminals provide output current, temperature, and output regulation status monitoring
• Jumper to margin output voltage ±2.5%
• VIOC pin of the LT3078 manages power dissipation and PSRR
• Banana jacks minimize VIN and VOUT connection voltage drops
• VO+, VO-, and VI+ terminals for regulation and dropout monitoring
• Configurable load-transient circuit for load response testing
• Thermally enhanced, 22-lead, 3mm × 4mm x 0.95mm, LQFN package
