Overview
The Panasonic AN79L08 is a monolithic, three-terminal fixed negative output voltage regulator designed for low-current applications. It provides a stabilized -8V DC output from an unstable input source without requiring external components. The device supports a maximum output current of 100mA and operates within a junction temperature range of 0°C to 125°C. Key electrical parameters include a typical line regulation of 160mV and load regulation of 80mV at 25°C. It features built-in overcurrent limiting and thermal overload protection circuits to ensure operational safety under fault conditions.
Feature Summary
- Provides stabilized fixed negative output voltage directly from unstable DC sources
- Requires no external components for basic operation
- Includes built-in overcurrent limit circuitry
- Incorporates thermal overload protection circuit
Applications
- Power circuits with current capacity up to 100mA
- General electronic equipment power supplies
- Household appliance control logic
- Communications equipment biasing
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 newer package codes indicate lead-free construction. Ensure input voltage polarity matches the negative regulator specification to prevent damage.
Selection Notes
Select this component when a stable negative rail is needed for low-power analog or digital loads. Verify that the input voltage remains within the absolute maximum rating of -35V. Consider the minimum input/output voltage difference requirement to maintain regulation. Evaluate thermal dissipation capabilities based on the expected ambient temperature and board copper area.
Part Context
The AN79L08 belongs to the AN79Lxx series of three-pin negative voltage regulators manufactured by Panasonic Electronic Components. This family offers various fixed output voltages ranging from -4V to -24V. The series is characterized by its simplicity, requiring minimal external circuitry, making it suitable for compact designs where space and component count are constrained.
Replacement Considerations
Compatible substitutes include other -8V negative linear regulators such as the LM7908 or MC79L08. When replacing, verify that the alternative device meets the 100mA current requirement and fits the physical footprint of the original SSIP or HSIP package.
