R1514H050B-T1-FE

Product Overview

The Nisshinbo Micro Devices Inc. R1514H050B-T1-FE is a linear voltage regulator IC intended for single-output positive fixed 5 V regulation with a maximum output current of 150 mA. It accepts an input voltage up to 36 V and uses a surface-mount SOT-89-5 package. The device includes an enable control feature and protection against over-current and over-temperature conditions. Its specified operating temperature range is -40°C to 105°C.

Key Features

• Positive fixed 5 V output regulator with a 150 mA output current rating.
• Maximum input voltage of 36 V supports regulation from higher-voltage supply rails.
• Voltage dropout is specified as 0.35 V at 20 mA.
• Quiescent current is specified as 20 µA.
• Enable control feature is available for output control.
• Integrated protection features include over-current and over-temperature protection.
• Surface-mount SOT-89-5 package.
• Operating temperature range of -40°C to 105°C.

Applications

• Regulating a fixed 5 V rail for low-current loads that require a positive linear supply.
• Stepping down a higher-voltage input to 5 V within the 150 mA output current limit.
• Controlling a single 5 V output through the enable feature during system power management.

Design & Procurement Notes

When selecting this regulator, verify that the input voltage remains at or below 36 V and that the load current does not exceed 150 mA. The 0.35 V dropout specification at 20 mA should be considered in headroom calculations, especially if the input supply approaches 5 V. The 20 µA quiescent current is relevant for low-power states, while the enable control can be used to manage output state. Board layout should account for the surface-mount SOT-89-5 package and thermal conditions within the -40°C to 105°C operating range. Over-current and over-temperature protection should be incorporated into system-level fault handling assumptions.
