Overview
The AN78L15 is a three-terminal fixed positive output monolithic voltage regulator from Panasonic's AN78Lxx series, designed for applications requiring up to 100 mA of output current. It provides a stabilized 15 V DC output from an unstable input source without external components. The device features built-in overcurrent limiting and thermal overload protection circuits. Electrical characteristics include a maximum input voltage of 35 V, a typical bias current of 110 mA at 25°C, and a minimum input-to-output differential voltage of 1.7 V. The unit operates within a junction temperature range of -55°C to +125°C.
Feature Summary
- Provides stable fixed positive output voltage without requiring external components
- Incorporates internal overcurrent limit circuitry for load protection
- Includes built-in thermal overload protection circuit to prevent damage during overheating
Applications
- Power supply circuits for general electronic equipment
- Local regulation in battery-powered systems
- Voltage reference sources for analog circuits
Procurement Notes
Verify the specific package variant (AN78L15 or AN78L15M) against design requirements, as pin configurations differ between SSIP and HSIP packages. Confirm lead-free status if RoHS compliance is mandatory, noting that newer package codes indicate lead-free construction. Ensure input voltage does not exceed absolute maximum ratings to avoid device failure.
Selection Notes
Select this component when a simple, low-cost linear regulation solution is needed for currents up to 100 mA. Consider the thermal dissipation capabilities relative to the ambient temperature and PCB copper area. Verify that the input voltage remains within the specified range to maintain proper line regulation and ripple rejection performance.
Part Context
This part belongs to the AN78Lxx series of three-pin positive voltage regulators manufactured by Panasonic Electronic Components. The series offers various fixed output voltages ranging from 4V to 24V. The AN78L15 specifically targets applications requiring a 15V rail with moderate current demands, serving as a standard replacement for legacy 78L15 designs in consumer and industrial electronics.
Replacement Considerations
Compatible substitutes include the STMicroelectronics L78L15ACUTR and generic 78L15 variants from other manufacturers. Verify pinout compatibility, particularly regarding the common ground pin position, as the AN78LxxM series uses a different pin assignment than the standard AN78Lxx series.
