Overview
The AN79L05 is a monolithic, fixed negative output voltage regulator from the Panasonic AN79Lxx series. It provides a stabilized -5V DC output with a maximum current capacity of 100mA directly from an unstable DC input without requiring external components. The device incorporates built-in overcurrent limit and thermal overload protection circuits to ensure reliable operation under varying load conditions.
Feature Summary
- Fixed negative output voltage regulation without external components
- Integrated overcurrent limiting circuit for short-circuit protection
- Built-in thermal overload protection circuit
Applications
- Power circuits requiring stable negative voltage rails
- General electronic equipment power supplies
- Communications equipment
- Measuring instruments
Procurement Notes
Verify the specific package variant (AN79Lxx or AN79LxxM) required for the design, as pinouts differ between SSIP and HSIP packages. Confirm lead-free status if environmental compliance is mandatory, noting that package types have transitioned to lead-free versions. Ensure input voltage remains within absolute maximum ratings to prevent damage.
Selection Notes
Select this component when a fixed -5V negative supply is needed for low-power applications up to 100mA. Consider the thermal dissipation characteristics and derating curves for high ambient temperatures. Verify that the input voltage range supports the required line regulation and minimum dropout voltage specifications for the intended operating conditions.
Part Context
The AN79L05 belongs to the AN79Lxx/AN79LxxM series of 3-pin negative output voltage regulators. This family includes twelve variants offering fixed output voltages ranging from -4V to -24V. All members share similar internal architectures featuring overcurrent and thermal protection, designed for use in standard electronic equipment power circuits.
Replacement Considerations
Compatible substitutes include other -5V negative linear regulators such as the L79L05 series. When replacing, verify pinout compatibility, as the AN79LxxM series uses a different pin configuration than the standard AN79Lxx series.
