Overview
The L78L15ACZ-TR is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series. It provides a fixed output voltage of 15 V with a maximum output current of 100 mA. The device operates within an input voltage range of 17.5 V to 30 V and supports an operating junction temperature range of 0 °C to 125 °C. Electrical characteristics include a line regulation of 300 mV (VI = 17.5 to 30 V) and a load regulation of 150 mV (IO = 1 to 100 mA). The quiescent current is typically 6.5 mA at 25 °C, and the dropout voltage is 1.7 V.
Feature Summary
- Internal current limiting and thermal shutdown protection mechanisms ensure robust operation under fault conditions.
- Designed as a direct replacement for Zener diode and resistor combinations, offering improved stability and lower noise.
- Requires no external components for basic fixed voltage regulation functionality.
Applications
- Local or on-card voltage regulation
- Elimination of noise associated with single-point regulation systems
- Construction of high-current regulators when used with power pass elements
Procurement Notes
Verify that the ordering suffix 'Z' corresponds to the TO-92 package and '-TR' indicates tape and reel packaging. Confirm the 'AC' designation matches the required ±4% output voltage tolerance. Ensure the component is sourced from authorized channels to guarantee authenticity and compliance with RoHS standards.
Selection Notes
Select this component for applications requiring a stable 15 V supply with currents up to 100 mA. The TO-92 package is suitable for through-hole mounting. Consider thermal dissipation requirements based on the input-output voltage differential and ambient temperature constraints.
Part Context
This part belongs to the L78L series of three-terminal positive regulators manufactured by STMicroelectronics. The series includes various fixed output voltages ranging from 3.3 V to 24 V. The L78L15 variant specifically targets 15 V regulation needs within this family.
Replacement Considerations
Compatible substitutes include UA78L15ACPK from Texas Instruments and MC78L15ACPRMG from onsemi. Verify pinout compatibility and thermal performance before substitution.
