Overview
The AN78L04ME1 is a 3-pin fixed positive output monolithic voltage regulator from the AN78LxxM series, manufactured by Panasonic Electronic Components. It provides a stabilized 4V DC output with a maximum current capacity of 100mA without requiring external components. The device features built-in overcurrent limiting and thermal overload protection circuits to ensure operational safety under fault conditions. It operates within an ambient temperature range of -30°C to +80°C and accepts input voltages up to 35V.
Feature Summary
- Integrated overcurrent limit circuit for short-circuit protection
- Built-in thermal overload protection circuit to prevent damage during overheating
- Requires no external components for basic voltage regulation
Applications
- Power supply circuits for general electronic equipment
- Voltage regulation in office equipment
- Voltage regulation in communications equipment
- Voltage regulation in measuring instruments
- Voltage regulation in household appliances
Procurement Notes
Verify that the specific part number matches the lead-free package designation HSIP003-P-0000Q as indicated in the datasheet updates. Confirm the operating temperature range requirements align with the specified -30°C to +80°C limit. Ensure input voltage does not exceed the absolute maximum rating of 35V to avoid device failure. Check for any recent product standard changes or discontinuation notices directly from Panasonic before finalizing procurement.
Selection Notes
Select this component when a fixed 4V positive output is required with a load current up to 100mA. It is suitable for applications where minimizing external component count is a priority. Consider the thermal dissipation characteristics if the input-output differential voltage is high at full load. Ensure the application environment stays within the specified ambient temperature limits to maintain reliable operation.
Part Context
This device belongs to the AN78Lxx/AN78LxxM Series of 3-pin positive output voltage regulators. The 'M' suffix typically denotes the surface-mount variant using the HSIP package, while the non-M version uses the through-hole SSIP package. The series offers multiple fixed output voltage options ranging from 4V to 24V, sharing similar internal protection structures and performance characteristics across the family.
Replacement Considerations
Direct substitutes include other AN78L04 variants such as the AN78L04 (through-hole) or AN78L04M. Verify pinout compatibility between HSIP and SSIP packages if changing form factors. Cross-reference with other manufacturers' 3-terminal 4V linear regulators only after confirming electrical parameter alignment and package dimensions.
