Overview
The L78L09ACZ is a three-terminal positive linear voltage regulator from the L78L series, manufactured by STMicroelectronics. It provides a fixed output voltage of 9V with a maximum output current of 100mA. The device features internal current limiting and thermal shutdown protection. It operates within an input voltage range up to 30V and supports junction temperatures from 0°C to 125°C. The component is housed in a TO-92-3 package.
Feature Summary
- Internal current limiting and thermal shutdown for robust operation
- No external components required for basic regulation
- Fixed 9V output with ±4% tolerance (A selection)
- Designed as a replacement for Zener diode/resistor combinations
Applications
- Local or on-card regulation
- Elimination of noise associated with single-point regulation
- High-current voltage regulators when used with power pass elements
Procurement Notes
Verify the specific suffix 'ACZ' corresponds to the desired accuracy class (±4%) and TO-92 package configuration. Confirm that the operating temperature range of 0°C to 125°C meets the application requirements. Ensure input voltage does not exceed the absolute maximum rating of 30V for this output voltage level.
Selection Notes
Select this component for applications requiring a simple, fixed 9V supply with moderate current demands up to 100mA. Consider the thermal resistance characteristics of the TO-92 package and ensure adequate heat dissipation if the power dissipation approaches internal limits. Verify compatibility with the system's ground reference and input voltage headroom.
Part Context
This part belongs to the L78Lxx series of three-terminal positive regulators. The series offers various fixed output voltages including 3.3V, 5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, and 24V. The 'A' designation indicates a tighter voltage tolerance compared to the 'C' variant.
