EK-265-111003 is a 1A low voltage LDO chip from ROHM. The chip is manufactured using CMOS technology and has low on-resistance and excellent load regulation. The output voltage range is 0.8V to 5.5V and can be set using an external resistor. The chip also has overcurrent protection and undervoltage protection functions.
The RP132x Series are CMOS-based LDO regulators offering a 1A output with low on-resistance. The series includes internally fixed versions (RP132S/Hxx1x, RP132J/Kxx1x) and externally adjustable versions (RP132x001x). Key features include an inrush current limit circuit limiting approximately 500mA upon startup, a thermal shutdown circuit stopping at 165°C, and excellent load regulation.
