R1130H Series
8V Input 300mA LDO with/without Adjust pin
The R1130H Series are CMOS-based LDO regulators featuring 300mA output. The input voltage (V
IN
) is as high as Max. 8V (maximum
rating of 9V). R1130H is available in two versions : the internally fixed output voltage type or the adjustable output voltage type by
external resistors. The CE pin can switch the regulator into standby mode.
