OUTLINE

The R1155x is a CMOS-based 24 V input voltage regulator featuring 150 mA output that provides high output

voltage accuracy and low supply current. Internally, the R1155x 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 offered in a 5-pin SOT-89-5 package and a 5-pin SOT-23-5 package.

FEATURES

Adjustable Output Voltage Type: 2.5 V, 2.5 V to 23.0 V
