Overview
The L78L05ABZ-AP is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in a TO-92 package. It provides a fixed output voltage of 5 V with an output current capability up to 100 mA. The device features internal current limiting and thermal shutdown protection. Electrical characteristics include a maximum input voltage of 30 V, a quiescent current of 6 mA at 25 °C, and line regulation of 150 mV. It operates within a junction temperature range of -40 °C to 125 °C.
Feature Summary
- Internal current limiting and thermal shutdown for robust operation
- Fixed 5 V output with ±4% tolerance
- No external components required for basic regulation
Applications
- Local or on-card voltage regulation
- Replacement for Zener diode/resistor combinations
- Power supply sections for electronic circuits
Procurement Notes
Verify the specific suffix 'AB' indicates the ±4% output voltage tolerance and extended temperature range compared to standard variants. Confirm the 'Z' designation corresponds to the TO-92 through-hole package and 'AP' aligns with the requested packaging format. Cross-reference the datasheet revision date to ensure electrical parameters match the production batch requirements.
Selection Notes
Select this component when a fixed 5 V rail is needed with moderate current demands up to 100 mA. The TO-92 package suits through-hole designs where space allows. Ensure the input voltage remains below the 30 V absolute maximum rating. Consider thermal dissipation capabilities if operating near the upper limits of the load current or ambient temperature.
Part Context
This part belongs to the L78Lxx family of low-current positive voltage regulators. The L78L series is designed as a compact alternative to larger packages like TO-220, offering similar functionality in a smaller footprint. It serves as a fundamental building block for power management in consumer electronics and industrial control systems requiring stable DC voltages.
Replacement Considerations
Compatible substitutes include other manufacturers' L78L05 equivalents such as UA78L05ACLPR from Texas Instruments or NCV78L05ABPRMG from onsemi, provided pinouts and electrical specifications are verified.
