L78L05ABZ-TR

Overview

The L78L05ABZ-TR is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in a TO-92-3 package. It provides a fixed output voltage of 5 V with an output current capability up to 100 mA. The device supports a maximum input voltage of 30 V and operates within a junction temperature range of -40 °C to +125 °C. Electrical characteristics include a typical quiescent current of 6 mA at 25 °C, line regulation of 150 mV (VI = 7.3 to 20 V), load regulation of 60 mV (IO = 1 to 100 mA), and supply voltage rejection of 49 dB at 120 Hz.

Feature Summary

Internal thermal overload protection and short-circuit protection ensure robust operation under fault conditions.
Designed for local or on-card regulation to eliminate noise and distribution problems associated with single-point regulation.
Requires no external components for basic fixed voltage regulation applications.

Applications

Local or on-card voltage regulation
Replacement for Zener diode/resistor combinations
Building blocks for high-current voltage regulators using power pass elements

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape-and-reel packaging rather than bulk or cut-tape formats when sourcing. Confirm the 'AB' designation indicates the specific ±4% output voltage tolerance and extended temperature range required for the application. Ensure compatibility with TO-92-3 through-hole mounting processes.

Selection Notes

Select this component when a fixed 5 V output is required with moderate current demands up to 100 mA. The 'AB' suffix denotes tighter voltage tolerance compared to standard variants. Consider the TO-92 package thermal resistance if operating near maximum current limits, as adequate heat sinking may be necessary to maintain performance within specified junction temperatures.

Part Context

This part belongs to the L78Lxx family of three-terminal positive regulators manufactured by STMicroelectronics. The series offers various fixed output voltages including 3.3, 5, 6, 8, 9, 10, 12, 15, 18, and 24 V. The L78L05 variant specifically targets 5 V regulation needs, while the 'AB' grade provides improved accuracy over the standard 'C' grade.
