150mA 24V Input LDO
The R1155x Series are CMOS-based 24V input voltage regulators featuring 150mA output that provide high output voltage accuracy and low supply current. Internally, a single IC consists of a voltage reference unit, an error amplifier, and a resistor net for setting output voltage. As protection circuits, the R1155x contains a current limit circuit, a fold-back protection circuit, a thermal shutdown circuit and a reverse current protection circuit.
The R1155x is available in the fixed output voltage type (R1155xxxxB), and the adjustable output voltage type (R1155x001C). The output voltage accuracy for the fixed output voltage type is as high as ±2.0%.
The R1155x is available in SOT-89-5 and SOT-23-5 packages.
