AN78L04

Overview

The AN78L04 is a 3-pin fixed positive output monolithic voltage regulator from the AN78Lxx series, manufactured by Panasonic Electronic Components. It provides a stabilized 4V DC output from an unstable input source without external components. The device supports a maximum output current of 100mA and features built-in overcurrent limiting and thermal overload protection circuits. Electrical characteristics include a line regulation of 145mV and load regulation of 10mV at 25°C. The package options are SSIP003-P-0000 and HSIP003-P-0000B.

Feature Summary

Fixed positive output voltage regulation without requiring external components
Integrated overcurrent limit circuit for short-circuit protection
Built-in thermal overload protection circuit to prevent damage during overheating

Applications

Power supply circuits requiring stable low-current voltage rails
General electronic equipment power conditioning
Office automation equipment internal voltage regulation

Procurement Notes

Verify the specific package type (SSIP or HSIP) required for your design, as dimensions differ. Confirm lead-free status if applicable, noting that packages may transition to SSIP003-P-0000S or HSIP003-P-0000Q variants. Always check the latest product standards before mass production to ensure specifications remain current.

Selection Notes

Select this component when a fixed 4V output with up to 100mA capacity is needed in a compact 3-pin form factor. Ensure the input voltage remains within the absolute maximum rating of 35V. Consider the thermal dissipation capabilities based on the chosen package and ambient temperature conditions to maintain junction temperature within safe limits.

Part Context

This part belongs to the AN78Lxx/AN78LxxM series of 3-pin positive voltage regulators. The series offers various fixed output voltages ranging from 4V to 24V. The 'L' designation indicates the 100mA current capacity class, distinguishing it from higher current variants. Panasonic manufactures these as monolithic integrated circuits for standard industrial and commercial applications.
