Renesas RTKA214035DE0000BU Manual

RTKA214035DE0000BU
The RTKA214035DE0000BU evaluation board
provides a simple platform to evaluate the 3.5×3.5mm
20-Ld QFN RAA214035 low-dropout linear regulator
(LDO).
RAA214035 is ultra-low noise, high PSRR LDO
regulators capable of sourcing up to 3A of load
current with very low dropout. These LDOs' output
voltage can be programmed from 0.5V to 3.65V by
means of 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.
The LDO operate from an input voltage of 1.4V to
6.5V without VBIAS and 1.1V to 6.5V with VBIAS.
