Overview
Description
The RTKA214035DE0000BU evaluation board provides a simple platform to evaluate the 3.5mm x 3.5mm 20-Ld QFN RAA214035 low-dropout linear regulator (LDO).
The RAA214035 is an ultra-low noise, high PSRR LDO regulator capable of sourcing up to 3A of load current with very low dropout. Its output voltage can be programmed from 0.5V to 3.65V using voltage setting pins on the IC in 50mV steps. The evaluation board has convenient jumpers to exercise these pins. For higher output voltage applications, external feedback resistors can still be used allowing the output voltage to be programmed anywhere from 0.5V to 5.1V.
Features
- Output voltage set IC pins easily programmed with JP_VSET
- Switch between voltage set IC pins or external resistor divider using jumper JP_FB
- Convenient shutdown mode function using Jumper JP_EN
- Power Good (PG) indication test point
- VBIAS banana jack or turret for applications where VIN < 1.4V
- BNC_VIN and BNC_VOUT connections for PSRR and output noise testing
Applications
- Sensor, imaging, and radar
- Test and measurement
- Instrumentation, medical, and audio
- RF power supplies
