Overview
The L79L06ABZ is a three-terminal negative linear voltage regulator from the L79L series by STMicroelectronics. It provides a fixed output voltage of -6 V with an output current capability up to 100 mA. The device features internal thermal overload protection and short-circuit protection, ensuring robust operation. It operates within a junction temperature range of -40 °C to +125 °C. The maximum DC input voltage is -30 V. The component is housed in a TO-92 package.
Feature Summary
- Integrated thermal overload and short-circuit protection mechanisms for enhanced reliability
- Fixed negative output voltage regulation without requiring external components
- Capable of delivering up to 100 mA output current when adequate heat sinking is provided
Applications
- Local or on-card regulation for electronic circuits
- Elimination of noise and distribution problems associated with single-point regulation
- Replacement for Zener diode and resistor combinations to improve output impedance
Procurement Notes
Verify that the specific part number matches the required tolerance and package type. Confirm the operating temperature range aligns with system requirements. Ensure proper heat sinking is designed into the PCB layout to support the maximum current rating. Check for any specific ordering suffixes if tape and reel packaging is needed instead of standard tube packaging.
Selection Notes
Select this component for applications requiring a stable negative voltage rail with moderate current demands. Consider the thermal resistance characteristics when designing the heat dissipation strategy. Evaluate the dropout voltage requirements against the available input voltage headroom. Compare line and load regulation specifications against circuit sensitivity needs.
Part Context
This component belongs to the L79L00 series of negative voltage regulators. The series includes various fixed output voltages such as -5 V, -8 V, -9 V, -12 V, and -15 V. The 'AB' designation indicates a wider operating temperature range compared to the 'AC' variant. The 'Z' suffix typically denotes the TO-92 through-hole package configuration.
Replacement Considerations
Compatible substitutes include other L79L06 variants from different manufacturers offering identical pinouts and electrical characteristics. Verify that replacement parts maintain the same -6 V output and 100 mA current rating. Ensure the alternative component supports the -40 °C to +125 °C temperature range.
