Overview
The AN79L04 is a monolithic, fixed negative output voltage regulator from the Panasonic AN79Lxx series. It provides a stabilized -4V DC output with a maximum current capacity of 100mA without requiring external components. The device features an absolute maximum input voltage rating of -35V and supports an operating ambient temperature range of -20°C to +80°C for the standard AN79Lxx variant. Electrical characteristics include a typical line regulation of 80mV and load regulation of 10mV at 25°C.
Feature Summary
- Integrated overcurrent limit circuitry
- Built-in thermal overload protection
- Requires no external components for operation
Applications
- Power circuits requiring stable negative voltage rails
- General electronic equipment power supplies
- Communications equipment
- Measuring instruments
Procurement Notes
Verify the specific package suffix (AN79L04 or AN79L04M) against the required operating temperature range before ordering. Confirm lead-free package availability if environmental compliance is mandatory. Check official documentation for any discontinuation status updates prior to finalizing procurement plans.
Selection Notes
Select this component when a fixed -4V negative supply is needed for low-current applications up to 100mA. Ensure the input voltage does not exceed the -35V absolute maximum rating. Consider the thermal dissipation requirements based on the selected package type and expected ambient temperature conditions.
Part Context
This part belongs to the AN79Lxx/AN79LxxM series of 3-pin negative output voltage regulators manufactured by Panasonic Industry. The series offers various fixed output voltages ranging from -4V to -24V in a compact surface-mount form factor designed for general-purpose power management tasks.
Replacement Considerations
Direct pin-to-pin replacements within the same Panasonic family include other variants such as AN79L05, AN79L06, AN79L07, AN79L08, AN79L09, AN79L10, AN79L12, AN79L15, AN79L18, AN79L20, and AN79L24, provided the specific output voltage requirement matches.
