Overview
The AN78L24M is a 3-pin fixed positive output monolithic voltage regulator from the AN78LxxM series by Panasonic. It provides a stabilized 24V output with a maximum current capacity of 100mA without external components. The device features built-in overcurrent limiting and thermal overload protection circuits. Electrical characteristics include an output voltage tolerance of ±4% (22.8V to 25.2V), line regulation of 60mV, and load regulation of 40mV at 25°C. It operates within an ambient temperature range of -30°C to +80°C for the AN78Lxx series and -55°C to +150°C storage temperature.
Feature Summary
- Provides stabilized fixed positive output voltage without requiring external parts
- Integrates built-in overcurrent limit circuit for short-circuit protection
- Includes thermal overload protection circuit to prevent damage during overheating
Applications
- Power circuits requiring up to 100mA current capacity
- General electronic equipment power supplies
- Office equipment and communications equipment
- Measuring instruments
Procurement Notes
Verify the specific package type and lead-free status before ordering, as Panasonic updated packages to SSIP003-P-0000S and HSIP003-P-0000Q. Confirm that the application does not require aerospace or life support systems, as these are excluded from standard warranties. Ensure input voltage remains within the absolute maximum rating of 40V to prevent device failure.
Selection Notes
Select this component when a fixed 24V supply is needed with minimal external circuitry. Consider the 1.7V minimum input/output voltage difference to ensure proper regulation under load. Evaluate thermal dissipation requirements based on the derating curve, as junction temperature limits must be respected. Verify compatibility with standard board mounting conditions for accurate thermal performance assessment.
Part Context
The AN78L24M belongs to the AN78Lxx/AN78LxxM series of 3-pin positive output voltage regulators. This family offers twelve fixed output voltage options ranging from 4V to 24V. The 'M' suffix typically denotes the SMD/SMT package variant, distinct from the through-hole SSIP/HSIP packages used in the standard AN78Lxx series. All variants share similar internal protection mechanisms and functional descriptions.
Replacement Considerations
Cross-reference with other manufacturers' 78L24 equivalents such as MC78L24ACPRP or L78L24ACUTR. Verify pinout configurations, as some alternatives may have different pin assignments for Input, Output, and Common. Check if the substitute meets the same 100mA current rating and thermal protection specifications.
