R1514H120B-T1-FE

Product Overview

The R1514H120B-T1-FE from Nisshinbo Micro Devices Inc. is a positive, fixed-output linear voltage regulator for applications requiring a regulated 12 V rail from a higher input voltage. The device provides a single 150 mA output and accepts input voltages up to 36 V. Its dropout voltage is 0.35 V at 20 mA, and its quiescent current is 20 µA. The regulator includes an enable control and protection against overcurrent, overtemperature, and short-circuit conditions. It operates from -40°C to 105°C and uses a surface-mount SOT-89-5 package.

Key Features

• Positive fixed-output regulator with one 12 V output
• Output current of 150 mA
• Maximum input voltage of 36 V
• Dropout voltage of 0.35 V at 20 mA
• Quiescent current of 20 µA
• Enable control feature
• Overcurrent, overtemperature, and short-circuit protection
• Operating temperature range of -40°C to 105°C
• Surface-mount SOT-89-5 package

Applications

• Fixed 12 V supply rails for embedded control boards
• Powering sensor, measurement, or peripheral modules that require a regulated positive voltage
• Point-of-load regulation in systems with input voltages up to 36 V
• Circuits where enable control can activate or disable a local 12 V rail

Design & Procurement Notes

When selecting this regulator, confirm that the required output current remains within 150 mA and that the input voltage does not exceed 36 V. The 0.35 V dropout figure at 20 mA should be considered when evaluating headroom between input and output. The enable control and protection features support controlled output management and fault response, while the 20 µA quiescent current is relevant for designs where idle power consumption matters. Layout and thermal design should account for the SOT-89-5 surface-mount package and the -40°C to 105°C operating range.
