Overview
Description
The RTKA214048DE0000BU evaluation board provides a simple platform to evaluate the 3.5mm × 3.5mm 20-Ld QFN RAA214048 low-dropout linear regulator (LDO).
RAA214048 is an ultra-low noise, high PSRR LDO regulator capable of sourcing up to 4A of load current with very low dropout. The output voltage can be programmed from 0.8V to 3.95V using voltage setting pins on the IC in 50mV steps. The evaluation board has convenient jumpers to exercise these pins. External feedback resistors can still be used for higher output voltage applications, allowing the output voltage to be programmed anywhere from 0.8V to 5.1V. The LDO operates from an input voltage of 1.4V to 6.5V without VBIAS and 1.1V to 6.5V with VBIAS.
Features
- Output voltage set pins easily programmed with JP_VSET
- Switch between voltage set 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
