Overview
The Panasonic AN77L04 is a three-pin positive output low dropout voltage regulator with a fixed 4V output and 100mA current capacity. It operates within an input voltage range of 4.66V to 14.66V, maintaining regulation with a typical minimum input/output differential of 0.23V at 50mA load. The device incorporates internal overcurrent limiting, thermal shutdown, rush current prevention, and input short-circuit protection circuits. It is available in SSIP003-P-0000 (TO-92) and HSIP003-P-0000B (SIP-3) packages.
Feature Summary
- Integrated protection mechanisms including overcurrent limiting, thermal shutdown, rush current prevention, and input short-circuit protection.
- Low dropout performance allowing stable regulation with minimal input-to-output voltage difference.
- Designed for battery-powered equipment and consumer or industrial applications experiencing supply voltage fluctuations.
Applications
- Battery-powered electronic devices
- Consumer electronics with variable supply voltages
- Industrial equipment requiring stabilized constant voltage power supplies
Procurement Notes
Verify the specific package variant required, as the AN77Lxx series utilizes both SSIP003-P-0000 and HSIP003-P-0000B form factors. Confirm lead-free status if applicable, noting that package dimensions may differ between standard and lead-free versions. Ensure external compensation capacitors meet ESR requirements to prevent oscillation under varying temperature conditions.
Selection Notes
Select the AN77L04 when a fixed 4V output is needed with up to 100mA load capability. Consider the HSIP003-P-0000B package for higher power dissipation capabilities on standard boards compared to the SSIP003-P-0000. Verify that the input voltage remains within the specified operating range to ensure proper line regulation and ripple rejection performance.
Part Context
The AN77L04 belongs to the AN77Lxx/AN77LxxM series of three-pin positive output low dropout voltage regulators manufactured by Panasonic Industry. This family provides various fixed output voltages ranging from 3V to 12V, all sharing a common 100mA output current rating and similar internal protection architectures for general-purpose voltage regulation tasks.
Replacement Considerations
The AN77L04M serves as the direct functional equivalent within the same series, offering identical electrical characteristics but potentially differing in package type or manufacturing revision. Cross-referencing pinout configurations is essential when substituting between different package styles such as SSIP and HSIP variants.
