Overview
The AN79L08M is a monolithic, fixed negative output voltage regulator providing an 8V DC supply. It operates with a maximum output current of 100mA and requires no external components for basic regulation. The device incorporates built-in overcurrent limiting and thermal overload protection circuits to ensure operational safety under fault conditions.
Feature Summary
- Integrated overcurrent limit circuit prevents damage during short-circuit events
- Built-in thermal overload protection circuit shuts down output when junction temperature exceeds safe limits
- Fixed negative output voltage eliminates the need for external feedback components
Applications
- Power circuits requiring stabilized negative voltage rails
- General electronic equipment power supplies
- Communications equipment biasing
- Measuring instrument internal power regulation
Procurement Notes
Verify the specific package variant (HSIP) against the latest Panasonic Industry specifications before ordering. Confirm lead-free status requirements as package types may have been updated. Ensure input voltage polarity matches the negative output configuration. Check application suitability against manufacturer restrictions regarding safety-critical systems.
Selection Notes
Select this component for applications requiring a stable -8V rail with low current demands up to 100mA. Consider the minimum input-output voltage difference required for regulation at the expected load current. Evaluate thermal dissipation capabilities based on the ambient temperature and board copper area available for heat spreading.
Part Context
This part belongs to the AN79LxxM series of three-pin negative regulators manufactured by Panasonic Electronic Components. The 'M' suffix typically denotes a specific package style within the family, distinct from the standard AN79Lxx series. The series offers various fixed voltage options ranging from -4V to -24V.
Replacement Considerations
Direct substitutes include other AN79L08 variants such as the AN79L08 without the M suffix, provided pinout compatibility is verified. Cross-brand equivalents like LM337-8 require careful evaluation of pin configurations and electrical parameter differences.
