Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific ordering suffix 'DDCR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the TSOT-23-6 footprint matches the target PCB layout dimensions. Ensure the application input voltage remains within the specified 0.9V to 5.5V range to maintain proper regulator operation. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when space constraints necessitate a small SOT-23-THIN package while requiring synchronous boost performance. It is suitable for applications needing an output voltage up to 5.5V driven by a single-cell lithium-ion or lithium-polymer battery. Consider the 1.2MHz fixed frequency for balancing component size against electromagnetic interference requirements. Evaluate the 500mA switch current limit against peak load demands to prevent saturation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6107x family of high-efficiency synchronous boost converters designed for mobile applications. The series typically includes variants with different current ratings or fixed output voltages. The TPS61071 specifically offers adjustable output control, distinguishing it from fixed-voltage counterparts within the same product line. It shares design resources and pinout compatibility with related models in the TPS61070-73 series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include TPS61070DDCR and TPS61072DDCR from Texas Instruments, which share identical pinouts and packages but differ in fixed output voltage settings or current capabilities.
