LM3480IM3-15/NOPB

Product Overview

The LM3480IM3-15/NOPB from Texas Instruments is a positive fixed-output linear voltage regulator intended for 15 V low-current regulation in surface-mount designs. The device provides a single 15 V output and is specified for output current up to 100 mA. It accepts input voltages up to 30 V and includes over-current and over-temperature protection. The regulator is packaged in a SOT-23-3 case and is rated for operation from -40°C to 125°C, supporting compact board layouts where a fixed 15 V rail is required.

Key Features

• Single positive fixed 15 V output with 100 mA maximum output current.
• Input voltage rating up to 30 V, with dropout voltage specified as 1.2 V at 100 mA.
• Quiescent current of 2 mA, suitable for low-current regulation tasks.
• Integrated over-current and over-temperature protection features.
• Surface-mount SOT-23-3 package for compact board implementation.

Applications

• 15 V supply rail for low-current analog or mixed-signal circuitry.
• Biasing or powering small signal-conditioning stages and sensor interfaces.
• Compact regulated 15 V rail in surface-mount embedded boards.

Design & Procurement Notes

Because the regulator is fixed at 15 V and limited to 100 mA, it is most appropriate for loads that do not require adjustable output or higher current. The 1.2 V dropout specification at 100 mA should be used when setting the minimum input-to-output voltage margin. The SOT-23-3 surface-mount package and 2 mA quiescent current should be considered for board area and baseline power consumption. The -40°C to 125°C operating range and the over-current and over-temperature protection features are relevant for defining safe operating conditions.
