Analog Devices LT3041 | Demoboard DC3158A

Description

The DC3158A evaluation board features the LT3041, a 20 V,1 A, ultra-low noise and ultra-high power-supply rejection ratio (PSRR), low-dropout (LDO) linear regulator that incorporates voltage input-to-output control (VIOC) tracking. VIOC allows control of the upstream switching converter to maintain a constant voltage across the LT3041 and, therefore, minimizes power dissipation and maintains PSRR.

Features

• Input voltage range: 3.8 V to 20 V
• Resistor-programmed 3.32 V output voltage
• Maximum output current: 1 A
• BNC connectors for noise and PSRR measurement
• Resistor programmed power-good
• Resistor-programmable current limit, current monitoring, and UVLO
• VIOC to manage power dissipation and PSRR
• Thermally enhanced, 14-lead, 3 mm × 4 mm, DFN package

Typical applications

• imaging and diagnostics
• RF power supplies: phase-locked loops, voltage-controlled oscillators, mixers, low-noise amplifiers, and power amplifiers ► Low-noise instrumentation ► High-speed and high-precision data converters
• Postregulator for switching supplies, RF power supplies
