Overview
The L78L06ABZ is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in a TO-92-3 package. It provides a fixed output voltage of 6 V with a maximum output current of 100 mA. The device supports an input voltage range up to 30 V and operates within a junction temperature range of -40 °C to +125 °C. Key electrical characteristics include a typical quiescent current of 6 mA, line regulation of 150 mV, load regulation of 60 mV, and a supply voltage rejection ratio (PSRR) of 46 dB at 120 Hz.
Feature Summary
- Internal current limiting and thermal shutdown protection ensure robust operation under fault conditions.
- Designed for local or on-card regulation to eliminate noise associated with single-point regulation.
- Capable of replacement for Zener diode/resistor combinations with improved performance.
- Requires no external components for basic fixed voltage regulation applications.
Applications
- Local or on-card voltage regulation
- Replacement for Zener diode and resistor combinations
- Power supply stages for motor control kits
Procurement Notes
Verify the specific suffix 'AB' indicates the ±4% output voltage tolerance and extended -40 °C to +125 °C operating temperature range compared to standard variants. Confirm the TO-92-3 through-hole package matches the design requirements. Ensure input voltage does not exceed the absolute maximum rating of 30 V for this output voltage level.
Selection Notes
Select this component when a fixed 6 V output is required with moderate current demands up to 100 mA. The AB suffix denotes tighter voltage tolerance and wider temperature range suitable for industrial environments. Consider thermal dissipation capabilities as power loss depends on the difference between input and output voltages multiplied by the load current.
Part Context
This part belongs to the L78Lxx series of three-terminal positive regulators manufactured by STMicroelectronics. The series offers various fixed output voltages including 3.3, 5, 6, 8, 9, 10, 12, 15, 18, and 24 V. The L78L series is designed for general-purpose linear regulation tasks where simplicity and reliability are prioritized over high efficiency.

FAQ
What is the output voltage tolerance for the L78L06ABZ?
The 'AB' suffix indicates a ±4% output voltage tolerance, providing tighter regulation compared to the standard ±8% tolerance found in 'C' suffix variants.
Does the L78L06ABZ require external capacitors for stability?
No external components are strictly required for basic operation, but the datasheet specifies test circuits using input and output capacitors (typically 0.33 µF and 0.1 µF) for optimal performance.
How does the L78L06ABZ protect against short circuits?
The device incorporates internal short-circuit protection that limits the output current, preventing damage to the regulator during overload conditions.
