Overview
The AN78M05NSPE1 is a monolithic positive voltage regulator from the AN78MxxNSP series, housed in an SP-3SU surface-mount package. It provides a fixed 5 V output with a maximum current capacity of 500 mA. The device operates within an ambient temperature range of -30°C to +85°C and accepts input voltages up to 35 V. Key electrical characteristics include a typical bias current of 46 mA and a ripple rejection ratio of 62 dB at 120 Hz.
Feature Summary
- Built-in overcurrent limit circuit
- Built-in thermal overload protection circuit
- Built-in ASO (area of safe operation) protection circuit
Applications
- Power circuits requiring stabilized fixed output voltage
- General electronic equipment
- Office equipment
- Communications equipment
- Measuring instruments
Procurement Notes
Verify that the specific ordering suffix matches the required lead-free package variant (SP-3SUA) if applicable, as Panasonic notes package changes. Confirm compliance with standard application guidelines, as the datasheet explicitly excludes automotive or life-support systems. Ensure design parameters strictly adhere to the guaranteed absolute maximum ratings and derating curves provided in the official documentation.
Selection Notes
Select this component for applications requiring a 5 V fixed output in a surface-mount configuration. Verify that the input voltage remains within the specified limits to prevent ASO shutdown. Consider the thermal resistance values based on the PCB copper area, as power dissipation capabilities vary significantly between glass epoxy and aluminum boards without external heat sinks.
Part Context
This part belongs to the AN78MxxNSP series, which includes nine fixed output voltage options ranging from 5 V to 18 V. All variants share identical pinouts and protective features, differing only in their regulated output levels. The series is designed for general-purpose power management in standard electronic equipment, offering a compact alternative to through-hole regulators.
Replacement Considerations
Direct substitutes include other Panasonic AN78Mxx series devices with different voltage outputs, such as AN78M06NSPE1 or AN78M12NSPE1, provided the voltage requirement differs. Cross-manufacturer equivalents like MC78M05CTG may be considered if package compatibility and thermal performance are verified against the SP-3SU dimensions.
FAQ
What is the operating junction temperature limit for thermal protection?
The internal circuit cuts off the output when the junction temperature exceeds 150°C.
Is this component suitable for automotive electronics?
No, the datasheet explicitly states that this IC is not suitable for car electronics equipment.
