L78L05ACZTR

Overview

The L78L05ACZTR 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 a maximum output current of 100 mA. The device accepts an input voltage range up to 30 V and operates within a junction temperature range of 0 °C to 125 °C. Electrical characteristics include a typical quiescent current of 6 mA, line regulation of 150 mV, load regulation of 60 mV, and supply voltage rejection of 49 dB at 120 Hz.

Feature Summary

Internal current limiting and thermal shutdown protection for robust operation
Fixed 5 V output without requiring external components
Designed for local or on-card regulation to eliminate noise

Applications

Local or on-card voltage regulation
Replacement for Zener diode and resistor combinations
Power management circuits requiring low noise

Procurement Notes

Verify that the component matches the specified L78L05ACZTR part number and TO-92-3 package configuration. Confirm the AC accuracy grade corresponds to the required ±4% output voltage tolerance. Ensure the ordering suffix indicates tape and reel packaging if automated assembly is intended. Cross-reference datasheet specifications against application requirements before finalizing procurement.

Selection Notes

Select this regulator when a fixed 5 V output is required with moderate current demands up to 100 mA. The AC grade offers tighter voltage tolerance compared to standard C grades. Consider the TO-92 package for through-hole mounting applications where space allows. Evaluate thermal dissipation needs based on the input-output voltage differential and load current.

Part Context

This component belongs to the L78Lxx family of three-terminal positive regulators manufactured by STMicroelectronics. The series includes various fixed output voltages ranging from 3.3 V to 24 V. The L78L05 variant specifically targets 5 V logic and analog circuit power supplies. The 'AC' designation indicates improved accuracy over the standard 'C' version.
