R1180D261B-TR-FE

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The R1180D261B-TR-FE is a CMOS-based low dropout regulator from the R1180x series, manufactured by Nisshinbo Micro Devices. It provides a fixed output voltage of 2.6 V with an accuracy of ±2.0%. The device supports a maximum output current of 150 mA and operates within an input voltage range of 1.7 V to 6.0 V. Key electrical characteristics include a typical supply current of 1 µA and a standby current of 0.1 µA when the Chip Enable pin is grounded. The IC features a built-in fold-back protection circuit limiting short-circuit current to approximately 40 mA. It utilizes a SON1612-6 package for surface mount applications.
