Renesas RTKA214045DE0000BU Manual

RTKA214045DE0000BU
The RTKA214045DE0000BU evaluation board
provides a simple platform to evaluate the 3.5×3.5mm
20-Ld QFN RAA214045
(LDO).
RAA214045 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 0.5V to 3.65V 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 0.5V 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.
