Rx5RZ Series
100mA LDO
No.EK-039-091101 CMOS LDO Regulator
The Rx5RZ Series are CMOS-based LDO regulators featuring 100mA output. The input voltage (VIN) can be set up to Max. 8V (absolute
maximum rating at 9V) and output voltage (VOUT) up to 6V. The SOT-23-5 package all ows the user to select the polarit y of the CE pin.
The SOT-89 package does not include the CE pin.
