Overview
The L78L08ABZ-AP is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in a TO-92 package. It provides a fixed output voltage of 8 V with an output current capability up to 100 mA. The device supports a maximum DC input voltage of 30 V and operates within a junction temperature range of -40 °C to +125 °C. It features internal thermal overload protection and short-circuit protection, eliminating the need for external components.
Feature Summary
- Integrates internal current limiting and thermal shutdown mechanisms for robust operation under fault conditions.
- Provides fixed 8 V regulation without requiring external feedback components.
- Offers ±4% output voltage tolerance for precise power supply applications.
Applications
- Local or on-card voltage regulation
- Replacement for Zener diode/resistor combinations
- Power pass element integration for high-current regulators
Procurement Notes
Verify that the ordering suffix 'Z' corresponds to the TO-92 through-hole package and '-AP' indicates environmental compliance status. Confirm the 'AB' designation matches the required -40 °C to +125 °C operating temperature range and ±4% accuracy specification before procurement.
Selection Notes
Select this component when a fixed 8 V output is required with up to 100 mA load current. Ensure the input voltage does not exceed 30 V and that the application environment falls within the specified -40 °C to +125 °C temperature limits. Verify thermal dissipation requirements based on the TO-92 package thermal resistance.
Part Context
This part belongs to the L78Lxx family of three-terminal positive regulators. The 'AB' suffix denotes extended temperature performance (-40 °C to +125 °C) compared to standard variants. The 'Z' indicates the TO-92 package style, while 'AP' typically signifies specific environmental compliance attributes defined by the manufacturer.
Replacement Considerations
Cross-reference with other L78L08 variants such as L78L08ACZ if the extended temperature range is not required. Ensure pinout compatibility between TO-92 packages from different manufacturers before substitution.
