• Features very small static circuit current suitable for dry cell sets
• Incorporates protective circuits for high reliability
• Supports stand-by condition with minimal external components

Applications

• Radio cassette recorders
• Dry cell operating sets
• Low frequency audio amplification

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead-free specifications and package details. Ensure compatibility with RoHS requirements if applicable. Confirm the exact pinout and thermal characteristics for your PCB layout before finalizing procurement. Cross-reference the datasheet revision history for any changes in outer lead surface process or mounting methods.

Selection Notes

Select this component for applications requiring a compact dual-channel power solution with low quiescent current. It is particularly suitable for battery-operated devices where power efficiency is critical. Consider the 3Ω load requirement and 15V supply voltage when designing the power stage. Evaluate the need for additional heat dissipation based on the expected continuous power output in your specific enclosure.

Part Context
