Overview
The L78L05CD13TR is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in an 8-SOIC surface-mount package. It provides a fixed 5V output with a maximum current capability of 100 mA and supports input voltages up to 30 V. The device incorporates internal thermal overload protection and short-circuit limiting, ensuring robust operation without requiring external components. It operates within a junction temperature range of 0°C to 125°C.
Feature Summary
- Integrated thermal overload protection prevents damage during excessive heat conditions.
- Built-in short-circuit protection safeguards the component against output faults.
- Requires no external components for basic regulation functionality.
- Designed for local or on-card voltage regulation applications.
Applications
- Local or on-card voltage regulation
- Elimination of noise associated with single-point regulation
- Replacement for Zener diode and resistor combinations
Procurement Notes
Verify the specific suffix 'C' indicates ±8% output voltage tolerance when reviewing datasheets. Confirm the SO-8 package variant matches the required PCB footprint. Ensure the operating environment stays within the specified 0°C to 125°C junction temperature range for reliable performance.
Selection Notes
Select this component for low-current applications requiring a fixed 5V supply. Consider the SO-8 package for surface-mount assembly needs. Evaluate thermal dissipation requirements if operating near the maximum 100 mA limit, as power handling depends on board copper area and ambient conditions.
Part Context
This part belongs to the L78Lxx family of three-terminal positive regulators. The 'C' designation specifies an 8% output voltage tolerance, distinguishing it from the higher precision 'A' variants. The 'D13TR' suffix denotes the SO-8 surface-mount package and tape-and-reel packaging format.
