RTKA214401DR0000BU
Demonstration Board
The RTKA214401DR0000BU demonstration board provides a simple and compact platform for demonstrating the
RAA214401, a 40V, 150mA LDO linear regulator with super low quiescent current. The board has convenient
connection points for the input and output. Its small size allows it to integrate into other systems as a daughter
card or a module.
The RAA214401 is offered in a 3Ld SOT23 package. The RTKA214401DR0000BU demonstration board operates
from a supply voltage as low as 4.5V up to 40V, regulates a 3.3V output voltage, and supports up to 150mA load.
Key Features
▪ Wide input voltage range 4.5V (at 10mA load) to 40V
▪ Accurate output voltage at 3.3V
▪ Excellent line and load regulation
▪ Stable with 2.2µF to 47µF MLCC output capacitor
▪ Robust line and load transient responses
▪ Integrated Fault protection including over temperature shut down and short circuit current limit
