Overview
The L79L08ACD is a three-terminal negative voltage regulator from the L79L series by STMicroelectronics. It provides a fixed output voltage of -8 V with an output current capability up to 100 mA. The device features internal current limiting and thermal shutdown protection, ensuring robust operation. It operates within a junction temperature range of 0 to 125 °C and accepts input voltages down to -30 V for this specific output level. The component is housed in an SO-8 surface-mount package.
Feature Summary
- Internal current limiting and thermal shutdown protection prevent damage under fault conditions.
- Designed as a fixed voltage regulator requiring no external components for basic operation.
- Offers improved output impedance compared to Zener diode/resistor combinations.
Applications
- Local or on-card regulation for noise elimination
- Replacement for Zener diode/resistor combinations
- Building high-current regulators with power pass elements
Procurement Notes
Verify the exact ordering code suffix against the manufacturer's official documentation to confirm package type and tape/reel availability. Ensure the selected variant matches the required operating temperature range and electrical specifications for your specific application design.
Selection Notes
Select the L79L08ACD when a stable -8 V negative supply is needed with moderate current requirements. Consider the SO-8 package for surface-mount assembly. Evaluate thermal dissipation needs based on the input-output voltage differential and load current to ensure operation within the specified junction temperature limits.
Part Context
This component belongs to the L79L00 series of 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, distinguishing it from the standard 'C' (±10%) and industrial 'AB' (-40°C to 125°C) grades.
Replacement Considerations
Compatible substitutes include other L79L08 variants like L79L08CD or L79L08ACU, provided the package and tolerance requirements are met. Cross-reference pinouts and thermal characteristics before substitution.
