Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the 'C' grade matches the required 0°C to +70°C operating temperature range. Ensure the SOIC-8 footprint aligns with PCB design constraints. Cross-reference the manufacturer part number with official Analog Devices documentation to validate RoHS compliance status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a low-cost, inductorless solution is required for moderate current applications up to 20 mA. It is suitable for designs where board space is limited and electromagnetic interference from inductors must be avoided. Consider the 10 kHz switching frequency limitations regarding output ripple requirements compared to higher-frequency alternatives.
