R1154N050B-TR-FE

Product Overview

The R1154N050B-TR-FE from Nisshinbo Micro Devices Inc. is a positive fixed-output linear voltage regulator in a SOT-23-5 surface-mount package. It provides a single 5 V output at up to 150 mA and accepts input voltages up to 24 V. The maximum dropout is 0.4 V at 150 mA, and quiescent current is 10 µA. An enable control feature supports power management in compact embedded systems, while over-current and over-temperature protection features are included. The operating temperature range is -40°C to 105°C (TA).

Key Features

• Positive fixed 5 V output from a single regulator
• 150 mA output current capability
• Maximum input voltage rating of 24 V
• Maximum dropout voltage of 0.4 V at 150 mA
• 10 µA quiescent current
• Enable control feature
• Over-current and over-temperature protection features
• Operating temperature range of -40°C to 105°C (TA)
• SOT-23-5 surface-mount package with SC-74A/SOT-753 case designation

Applications

• Low-current 5 V supply for microcontroller and logic circuits
• Power sequencing or enable-controlled rails in battery-powered embedded boards
• Compact surface-mount linear regulation stage for control and instrumentation boards

Design & Procurement Notes

When using this regulator, the input voltage must remain below the 24 V maximum while also providing enough headroom above the 5 V output for the 0.4 V dropout at 150 mA. The enable feature allows the regulator to be turned on or off under system control, which can be useful for power sequencing or standby modes. Because the quiescent current is 10 µA, the part is suitable for designs where low idle consumption is important. The 150 mA output limit, linear topology, and over-current and over-temperature protection features should be considered during load selection and thermal layout. The device uses a surface-mount SOT-23-5 package and is rated for -40°C to 105°C (TA).
