Analog Devices LT3041 | Demoboard DC3158A
Evaluating the LT3041 20 V, 1 A, Ultra-Low Noise, Ultra-High PSRR Linear Regulator with VIOC Control
Overview
| Topology | Other Topology |
| Input voltage | 3.8-20 V |
| Output 1 | 3.32 V / 1 A |
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
- Postregulator for switching supplies, RF power supplies
- 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
