Overview
The L78L08ABZ is a three-terminal positive linear voltage regulator from the L78L series, manufactured 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. It operates within a junction temperature range of -40 °C to +125 °C. The maximum DC input voltage is 30 V for this output level. The quiescent current is typically 6 mA at 25 °C. Line regulation is specified at 175 mV (VI = 10.5 to 23 V) and load regulation at 80 mV (IO = 1 to 100 mA). The supply voltage rejection ratio is typically 45 dB at 120 Hz. The component is housed in a TO-92 package.
Feature Summary
- Internal current limiting and thermal shutdown protection ensure robust operation under fault conditions.
- Designed as a fixed voltage regulator suitable for local or on-card regulation applications.
- Functions as a replacement for Zener diode/resistor combinations with improved performance characteristics.
Applications
- Local or on-card voltage regulation
- Elimination of noise associated with single-point regulation
- Replacement for Zener diode/resistor combinations
Procurement Notes
Verify the specific suffix 'Z' corresponds to the TO-92 through-hole package configuration required for your design. Confirm that the 'AB' designation aligns with the necessary operating temperature range and voltage tolerance specifications. Ensure compatibility with the intended PCB footprint and mounting style before finalizing procurement orders.
Selection Notes
Select this component when a fixed 8 V output is required with up to 100 mA load current. The TO-92 package is appropriate for through-hole mounting. Consider the thermal resistance characteristics if heat dissipation is a concern. Verify that the input voltage remains within the 30 V maximum limit for the 8 V output variant.
Part Context
This part belongs to the L78L series of three-terminal positive regulators. The series offers various fixed output voltages including 3.3, 5, 6, 8, 9, 10, 12, 15, 18, and 24 V. The 'A' selection indicates a tighter voltage tolerance compared to the 'C' selection. The series is designed for general-purpose power management tasks requiring simple regulation without external components.
