The R1171x Series are CMOS-based LDO regulators featuring 2A/1.5A output. The TO-252-5-P1 and the HSOP-6J that support high wattage can provide the output current up to 2A and 1.5A, respectively. 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, R1171x has a thermal shutdown circuit. Ceramic capacitors can be used.
The R1171x Series are CMOS-based Low Dropout (LDO) regulators available in TO-252-5-P1 and HSOP-6J packages, supporting high wattage outputs of up to 2A and 1.5A respectively. The series features a significantly lower dropout voltage compared to bipolar regulators and includes protection circuits such as fold-back current limiting and thermal shutdown.
