R1154N033B-TR-FE

Product Overview

The R1154N033B-TR-FE from Nisshinbo Micro Devices Inc. is a single-output, positive, fixed linear voltage regulator in a surface-mount SOT-23-5 package. It provides a fixed 3.3V output at up to 150mA and accepts an input voltage up to 24V. The device includes an enable control and protection against overcurrent and overtemperature, with a maximum dropout voltage of 0.4V at 150mA. Its specified operating ambient temperature range is -40°C to 105°C. The regulator is offered in the R1154x series.

Key Features

• Single positive fixed output with 3.3V output and 150mA current rating
• Maximum input voltage of 24V
• Maximum dropout voltage of 0.4V at 150mA
• Quiescent current of 10 µA
• Enable control with overcurrent and overtemperature protection
• Surface-mount SOT-23-5 package with -40°C to 105°C ambient operating range

Applications

• Low-current 3.3V supply rails for logic, sensors, and communication peripherals
• Compact surface-mount power management on boards using SOT-23-5 footprints
• Regulated 3.3V outputs in systems that use enable control for sequencing or standby
• Power rails where 10 µA quiescent current supports low idle-power requirements

Design & Procurement Notes

For design use, verify that the input rail remains above the 3.3V output by the specified dropout margin at the intended load, and that the total output current does not exceed 150mA. The enable control can be used to place the regulator in a disabled state during system sequencing or standby, while the 10 µA quiescent current is relevant for power-budget calculations. Board layout should account for the -40°C to 105°C ambient operating range and the overtemperature protection behavior. For procurement and PCB preparation, confirm that the SOT-23-5, SC-74A, or SOT-753 package designation matches the intended land pattern and assembly process.
