CAT6221-SPTD-GT3

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The CAT6221-SPTD-GT3 is a dual-output low-dropout (LDO) linear voltage regulator manufactured by onsemi. It features two independent output channels, each capable of delivering up to 300 mA of continuous current. The device operates within an input voltage range of 2.3 V to 5.5 V and provides fixed output voltages of 3.0 V per channel. Packaged in a compact TSOT-23-6 surface-mount format, it supports operation across an extended temperature range from -40°C to +125°C. Key electrical specifications include a maximum line regulation of 0.4%/V and load regulation of 2%, ensuring stable performance under varying conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'SPTD' against official onsemi documentation to confirm exact output voltage configurations and pin assignments. Ensure compatibility with your PCB footprint design, specifically the TSOT-23-6 package dimensions. Cross-reference thermal requirements with your application's heat dissipation constraints before finalizing procurement decisions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when dual-channel power regulation is required within a limited board space. The 300 mA per channel rating suits moderate load applications. Consider the fixed 3.0 V output configuration; if adjustable outputs are needed, alternative models like the CAT6219ADJTD-GT3 should be evaluated instead. Verify input voltage stability to ensure adequate dropout margin for reliable regulation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the CAT6221 series of dual LDO regulators from onsemi. It complements single-channel variants like the CAT6219 and other PMIC offerings in the manufacturer's portfolio. The series is designed for cost-sensitive, space-constrained applications requiring efficient power management without the complexity of switching regulators.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

For direct replacements, consider the CAT6221-PPTD-GT3 or CAT6221-QPTD-GT3, which share the same dual-channel architecture and TSOT-23-6 packaging. Verify that the output voltage ratings match your circuit requirements, as different suffixes may indicate distinct fixed voltage options.
