Rx5RZ Series
100mA LDO
The Rx5RZ Series are CMOS-based LDO regulators featuring 100mA output. The input voltage (V
IN
) can be set up to Max. 8V (absolute
maximum rating at 9V) and output voltage (V
OUT
) up to 6V. The SOT-23-5 package allows the user to select the polarity of the CE pin.
The SOT-89 package does not include the CE pin.
