Overview
The AN79L20 is a monolithic, fixed negative output voltage regulator from the Panasonic AN79Lxx series. It provides a stabilized -20V DC output with a maximum current capacity of 100mA. The device operates without external components and includes built-in overcurrent limiting and thermal overload protection circuits. It accepts an unstable DC input voltage to generate the regulated output.
Feature Summary
- Fixed negative output voltage generation
- Integrated overcurrent limit circuit
- Built-in thermal overload protection
Applications
- Power supply circuits requiring stable negative voltage rails
- Electronic equipment utilizing standard power regulation
- General-purpose electronic devices
Procurement Notes
Verify that the specific ordering suffix matches the required package type (SSIP or HSIP) and lead-free status (S or Q suffixes). Confirm compliance with RoHS directives for the intended application environment. Ensure the selected variant meets the absolute maximum ratings for input voltage and power dissipation under your operating conditions.
Selection Notes
Select this component when a fixed -20V negative rail is required for low-current applications up to 100mA. Consider the thermal characteristics and derating curves if the ambient temperature exceeds standard ranges. Verify that the input voltage range supports the necessary dropout voltage for the specific load conditions.
Part Context
This part belongs to the AN79Lxx/AN79LxxM series of 3-pin negative output voltage regulators manufactured by Panasonic Electronic Components. The series offers twelve different fixed output voltages ranging from -4V to -24V, designed for use in various power circuits where compact size and simple implementation are prioritized.
Replacement Considerations
Check datasheets for other -20V negative linear regulators offering similar 100mA current capabilities. Verify pinout compatibility and thermal performance metrics before substitution.
