Overview
The L78L15ABZ-AP 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 15 V with an output current capability up to 100 mA. The maximum DC input voltage is rated at 35 V. The device operates within a junction temperature range of -40 °C to +125 °C and features ±4% output voltage tolerance.
Feature Summary
- Integrates internal thermal overload protection and short-circuit limiting for robust operation
- Requires no external components for basic regulation functionality
- Offers improved performance over Zener diode/resistor combinations with lower quiescent current
Applications
- Local or on-card voltage regulation
- Elimination of noise associated with single-point regulation
- Replacement for Zener diode and resistor networks
Procurement Notes
Verify that the specific part number matches the required voltage tolerance and operating temperature range. Confirm the package type corresponds to the intended PCB layout. Ensure compliance with environmental directives such as RoHS if applicable to the manufacturing process.
Selection Notes
Select this component when a fixed 15 V output is required with moderate current demands. Consider the thermal resistance characteristics of the TO-92 package for heat dissipation requirements. Verify input voltage stability remains within the specified maximum limits under all operating conditions.
Part Context
This device belongs to the L78L family of low-current positive regulators. It shares architectural similarities with other members of the series but is distinguished by its specific 15 V output setting and extended industrial temperature rating provided by the 'AB' designation.
Replacement Considerations
Direct pin-compatible substitutes include the L78L15ACZ-AP for commercial temperature ranges. Cross-manufacturer equivalents such as the UA78L15ACLPR may be evaluated for functional compatibility.
