AN78L07M

Overview

The AN78L07M is a 3-pin fixed positive output monolithic voltage regulator providing a nominal 7V DC output. It supports a maximum continuous output current of 100mA and accepts input voltages up to 22V. The device features built-in overcurrent limiting and thermal overload protection circuits. Electrical characteristics include a line regulation of 70mV and load regulation of 13mV at 25°C. It operates within an ambient temperature range of -30°C to +80°C.

Feature Summary

• Provides stabilized fixed output voltage from unstable DC input without external components
• Integrates internal overcurrent limit circuit for short-circuit protection
• Includes thermal overload protection circuit to prevent damage during overheating

Applications

• Power supply circuits requiring low current capacity
• General electronic equipment power regulation
• Office equipment voltage stabilization
• Communications equipment power management

Procurement Notes

Verify the specific package variant (SSIP or HSIP) against the design schematic, as pin configurations differ between series. Confirm lead-free status if required by environmental compliance standards. Ensure input voltage remains within absolute maximum ratings to avoid thermal shutdown or permanent damage. Check latest datasheets for any specification updates prior to final production.

Selection Notes

Select this component when a fixed 7V output with 100mA capability is required in a compact form factor. Consider the minimum input/output voltage difference of approximately 1.7V when designing the input stage. Evaluate thermal dissipation requirements based on the expected ambient temperature and load conditions to ensure operation within safe junction temperatures.

Part Context

This part belongs to the AN78Lxx/AN78LxxM series of 3-pin positive voltage regulators manufactured by Panasonic Electronic Components. The series offers various fixed output voltages ranging from 4V to 24V. The 'M' suffix typically denotes a specific package type or revision within the product family, distinct from the standard AN78Lxx series packaging.

Replacement Considerations

Cross-reference with other 78L07 compatible parts from different manufacturers only after verifying pinout compatibility and electrical parameter alignment. Note that package dimensions and pin assignments may vary between suppliers; physical fitment must be confirmed before substitution.
