L78L06ABUTR

Overview

The L78L06ABUTR is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in an SOT-89 surface-mount package. It provides a fixed output voltage of 6 V with a maximum output current of 100 mA. The device features internal current limiting and thermal shutdown protection. It operates within an extended junction temperature range of -40 °C to +125 °C. Input voltage can reach up to 30 V for this output level.

Feature Summary

• Integrated short-circuit and thermal overload protection mechanisms
• Requires no external components for basic fixed voltage regulation
• Capable of local on-card regulation to eliminate distribution noise

Applications

• Local or on-card voltage regulation
• Replacement for Zener diode and resistor combinations
• Construction of high-current regulators using power pass elements

Procurement Notes

Verify that the specific ordering suffix matches the required SOT-89 tape and reel packaging configuration. Confirm the AB designation aligns with the necessary extended temperature range specifications (-40 °C to +125 °C) for your operational environment before finalizing procurement.

Selection Notes

Select this component when a fixed 6 V supply is required at currents up to 100 mA. The SOT-89 package is suitable for surface-mount applications where space efficiency is prioritized over the higher thermal dissipation capabilities of through-hole packages like TO-92.

Part Context

This part belongs to the L78Lxx family of three-terminal positive regulators. The 'AB' suffix indicates availability in the extended industrial temperature range compared to standard commercial grades. The 'UTR' suffix denotes the specific SOT-89 surface-mount package variant supplied in tape and reel format.
