Description
The R1170 Series are CMOS-based LDO regulators featuring 800mA output. The CMOS process provides both high output current and low supply current. The dropout voltage is significantly lower than bipolar regulators. The CE pin can switch the regulator into standby mode. In addition to a fold-back protection circuit built into conventional LDO regulators, R1170 has a thermal shutdown circuit.
