L78L12ACZ-TR

Overview

The L78L12ACZ-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 12 V with a maximum output current of 100 mA. The device supports a maximum input voltage of 35 V and operates within a junction temperature range of 0 °C to 125 °C. It features internal thermal overload protection and short-circuit protection.

Feature Summary

Internal current limiting and thermal shutdown mechanisms 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
General-purpose power supply circuits

Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging configuration. Confirm the specific tolerance grade (A for ±4%) aligns with design requirements. Ensure the TO-92-3 through-hole package is compatible with the target PCB footprint and assembly process.

Selection Notes

Select this component when a fixed 12 V output at up to 100 mA is required in a compact through-hole package. Consider the 35 V maximum input voltage limit and the need for adequate heat dissipation to maintain performance within the specified operating temperature range.

Part Context

This part belongs to the L78Lxx family of low-current positive voltage regulators. The 'A' designation indicates a tighter output voltage tolerance compared to the standard 'C' variant. The '-TR' suffix denotes the tape and reel packaging format suitable for automated surface-mount or through-hole insertion equipment.
