L79L15ACD

Overview

The L79L15ACD is a three-terminal negative linear voltage regulator from the L79L00 series, manufactured by STMicroelectronics. It provides a fixed output voltage of -15 V with a maximum output current of 100 mA. The device accepts an input voltage range up to -30 V for lower voltage variants and up to -35 V for the -12 V and -15 V outputs. It operates within a junction temperature range of 0°C to 125°C. The component is housed in an SO-8 surface-mount package.

Feature Summary

Integrates internal thermal overload protection and short-circuit protection for robust operation.
Functions as a direct replacement for Zener diode and resistor combinations, offering improved output impedance and lower noise.
Requires no external components for basic regulation functionality.
Designed for local or on-card regulation to eliminate distribution problems associated with single-point regulation.

Applications

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

Procurement Notes

Verify the specific suffix 'D' corresponds to the SO-8 package configuration when ordering. Confirm that the AC grade selection meets the required ±5% output voltage tolerance specifications for the application. Ensure the design accounts for the thermal resistance characteristics of the SO-8 package to maintain safe operating temperatures under load.

Selection Notes

Select this component for applications requiring a stable negative -15 V supply with currents up to 100 mA. The AC variant offers tighter voltage tolerance compared to the standard C grade. Consider the SO-8 package for surface-mount assembly requirements. Evaluate thermal dissipation needs based on the input-output voltage differential and ambient conditions.

Part Context

This part belongs to the L79L00 series of low-power negative voltage regulators. The series includes various fixed output voltages such as -5 V, -6 V, -8 V, -9 V, -12 V, and -15 V. The 'AC' designation indicates a ±5% output voltage tolerance, while the 'D' suffix specifies the SO-8 surface-mount package type.
