Overview
The L78L09ACZ-TR 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 9V with a maximum output current of 100 mA. The device supports a maximum input voltage of 30V and operates within a junction temperature range of 0°C to 125°C. It features internal current limiting and thermal shutdown protection.
Feature Summary
- Internal current limiting and thermal shutdown for robust operation
- No external components required for basic regulation
- Available in ±8% output voltage tolerance selection
Applications
- Local or on-card voltage regulation
- Elimination of noise and distribution problems associated with single-point regulation
- Replacement for Zener diode/resistor combinations
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm that the component grade aligns with industrial operating temperature requirements. Ensure the selected part number corresponds to the correct voltage tolerance specification for the design.
Selection Notes
Select this component when a fixed 9V output is required with up to 100 mA load capability. Consider the TO-92 package for through-hole mounting applications. Evaluate thermal dissipation needs based on the input-output voltage differential and ambient operating conditions.
Part Context
This part belongs to the L78Lxx family of low-current positive regulators. The 'C' designation indicates an 8% output voltage tolerance, while the 'Z' suffix specifies the TO-92 package type. The '-TR' suffix denotes the tape and reel packaging format intended for automated assembly processes.
FAQ
What is the output voltage tolerance for the L78L09ACZ-TR?
The 'C' in the part number indicates an output voltage tolerance of ±8%.
Does the L78L09ACZ-TR require external capacitors for stability?
No external components are strictly required for basic operation, though typical application circuits may include input and output capacitors for improved transient response.
