Overview
The AN79L05M is a 3-pin fixed negative output monolithic voltage regulator from the AN79LxxM series, manufactured by Panasonic. It provides a nominal output voltage of -5V with a typical tolerance of ±100mV at 25°C. The device supports a maximum output current of 100mA and operates within an ambient temperature range of -20°C to +80°C. Key electrical parameters include a line regulation of 100mV (VI = -9V to -19V) and load regulation of 11mV (IO = 1 to 100mA). It features built-in overcurrent limiting and thermal overload protection circuits.
Feature Summary
- Integrated overcurrent limit circuit for short-circuit protection
- Built-in thermal overload protection circuit
- Requires no external components for basic operation
Applications
- Power circuits requiring stabilized negative DC voltage
- General electronic equipment power supplies
- Household appliances
- Communications equipment
Procurement Notes
Verify that the specific part number matches the HSIP003-P-0000B package type. Confirm lead-free status if required, as datasheet notes transition to SSIP003-P-0000S and HSIP003-P-0000Q packages. Ensure application conditions comply with absolute maximum ratings regarding input voltage and power dissipation derating curves.
Selection Notes
Select this component when a fixed -5V negative rail is needed with up to 100mA capacity. Consider the HSIP003-P-0000B package dimensions for PCB layout. Verify that the input voltage range (-9V to -19V typical test condition) accommodates the system's supply variations. Check thermal requirements against the 650mW power dissipation rating.
Part Context
The AN79L05M belongs to the AN79Lxx/AN79LxxM series of 3-pin negative output voltage regulators. This series offers 12 types of fixed output voltages ranging from -4V to -24V. The 'M' suffix typically denotes the HSIP package variant, distinct from the standard AN79Lxx series which uses the SSIP package.
Replacement Considerations
Cross-reference with other manufacturers' 79L05 equivalents. Verify pinout compatibility, specifically noting that Pin 1 is Common, Pin 2 is Input, and Pin 3 is Output for the AN79LxxM series.
FAQ
What are the pin assignments for the AN79L05M?
Pin 1 is Common, Pin 2 is Input, and Pin 3 is Output.
Does the AN79L05M require external capacitors?
No external components are strictly required for basic operation, but a 2µF input capacitor (CI) is recommended if the wiring from the smoothing circuit is long, and a 1µF output capacitor (CO) improves transient response.
