CAT6221-MPTD-GT3

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

The CAT6221-MPTD-GT3 is a dual-output low-dropout (LDO) linear voltage regulator manufactured by onsemi. It features two independent channels, each capable of delivering up to 300mA of output current. The device operates with an input voltage range from 2.3V to 5.5V and supports fixed output voltages. Packaged in a compact TSOT-23-6 surface-mount format, it is designed for space-constrained applications requiring efficient power management with low quiescent current consumption.

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

Verify the specific output voltage configuration required for your application, as the CAT6221 series offers various fixed voltage options. Confirm package availability and lead times through authorized onsemi distributors. Ensure thermal management considerations are addressed given the 300mA per channel capability in the small TSOT-23-6 package. Check for any recent product change notices or lifecycle status updates directly from onsemi documentation before finalizing procurement plans.

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

Select this component when dual isolated or non-isolated LDO outputs are needed from a single package. Compare against single-channel alternatives if only one rail is required to optimize cost and board space. Consider the input voltage range relative to your battery or supply source. Evaluate thermal performance under maximum load conditions to ensure reliable operation within the specified temperature range.

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

The CAT6221 belongs to onsemi's CAT62xx family of low-power LDO regulators. This family emphasizes low noise and high power supply rejection ratio (PSRR) for sensitive analog circuits. The dual-output variant integrates two complete regulator circuits into one compact footprint, reducing component count compared to using two separate single-channel LDOs. It complements other PMIC solutions in portable and industrial markets.

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

Direct pin-to-pin replacements may include other dual-output LDOs from onsemi such as the CAT6221-SFTD-GT3 or CAT6221-PPTD-GT3, depending on the required output voltage. Verify electrical specifications match exactly, particularly output current and voltage tolerance. Cross-reference with competitors like TI or ST for equivalent dual LDO packages if onsemi parts are unavailable.
