AN78L15M

Overview

The AN78L15M is a 3-pin, fixed positive output monolithic voltage regulator from the AN78LxxM series. It provides a stabilized 15 V DC output from an unstable input source without requiring external components. The device supports a maximum output current of 100 mA and operates within a supply voltage range of 17.5 V to 30 V. It utilizes a 3-pin plastic single inline package with heat sink (HSIP003-P-0000Q) and incorporates built-in overcurrent limit and thermal overload protection circuits.

Feature Summary

• Fixed 15 V positive output capability
• Integrated overcurrent limiting circuit
• Built-in thermal overload protection
• No external components required for operation

Applications

• Power circuits requiring up to 100 mA capacity
• General electronic equipment power supplies
• Office equipment power regulation
• Communications equipment power management
• Measuring instruments power regulation

Procurement Notes

Verify the specific lifecycle status on the Panasonic semiconductor website before procurement, as the datasheet indicates maintenance or discontinuation stages. Confirm that the HSIP003-P-0000Q package code matches the design requirements. Ensure compliance with export control laws if applicable. Consult sales staff for special applications involving aerospace, automotive, or life support systems, as these are not covered by standard specifications.

Selection Notes

Select this component when a fixed 15 V positive rail is needed with a maximum load of 100 mA. The operating supply voltage must remain between 17.5 V and 30 V. Consider the thermal dissipation limits at ambient temperatures up to 80°C. The internal protection features simplify design by removing the need for external safety components. Verify junction temperature constraints during high-load operations.

Part Context

This part belongs to the AN78LxxM series of 3-pin positive output voltage regulators. The series offers twelve fixed voltage options ranging from 4 V to 24 V. All variants share the same monolithic silicon bipolar IC construction and package style. The AN78L15M specifically targets applications requiring a stable 15 V supply in compact designs.

Replacement Considerations

Consult the official Panasonic cross-reference tools for verified substitutes. Generic replacements may differ in pinout, thermal characteristics, or protection features. Verify compatibility with existing PCB layouts and thermal management strategies before substitution.
