NJM7805SDL1-TE1

Product Overview

The NJM7805SDL1-TE1 from Nisshinbo Micro Devices Inc. is a positive fixed-output linear voltage regulator for single-output 5V regulation. It supplies up to 1.5A from an input voltage up to 35V and uses a surface-mount TO-252-3, DPAK package with two leads and a tab. The device includes over-current and over-temperature protection, supports operation from -40°C to 125°C, and has a maximum dropout of 2.2V at 1.5A. Its 6 mA quiescent current and 78dB power-supply ripple rejection at 120Hz support regulated power delivery in board-level designs.

Key Features

• Fixed 5V output with 1.5A output current capability.
• Maximum input voltage of 35V.
• Maximum dropout voltage of 2.2V at 1.5A.
• Over-current and over-temperature protection features.
• Quiescent current of 6 mA and PSRR of 78dB at 120Hz.
• Operating temperature range from -40°C to 125°C.
• Surface-mount TO-252-3, DPAK package with two leads and tab.

Applications

• Regulated 5V rail for microcontroller, logic, or interface boards.
• Powering sensors, instrumentation modules, or control circuits.
• Local regulation from a higher-voltage DC bus in board assemblies.

Design & Procurement Notes

Designers should confirm that the input voltage remains below the 35V maximum while providing enough headroom above 5V to maintain regulation under load. Because the maximum dropout is 2.2V at 1.5A, the input supply should be selected to avoid excessive voltage drop under worst-case load and temperature conditions. The TO-252-3 DPAK package supports surface-mount assembly and includes a tab that should be considered in layout and thermal planning. The 6 mA quiescent current and 78dB ripple rejection at 120Hz are relevant for power-path and noise budgeting, while the over-current and over-temperature protections define part of the device's fault behavior. The -40°C to 125°C operating range should be checked against the intended board environment.
