CAT6218-330TDGT3

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

The CAT6218-330TDGT3 is a fixed positive single-output Low Dropout (LDO) voltage regulator manufactured by onsemi. It provides a nominal output voltage of 3.3 V with a maximum output current capability of 300 mA. The device features a typical dropout voltage of 0.3 V at full load and supports an input voltage range from 2.3 V to 5.5 V. It operates within a junction temperature range of -40 °C to +125 °C and is housed in a TSOT-23-5 surface-mount package.

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

Verify the specific suffix TDGT3 against the manufacturer's official datasheet to confirm pinout, tolerance, and packaging details. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to confirm current availability status and lead times prior to finalizing procurement plans.

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

Select this regulator when a fixed 3.3 V rail is required with moderate current demands up to 300 mA. It is appropriate for designs where low noise and high line/load regulation are prioritized over switching efficiency. Consider the thermal performance in the TSOT-23 package relative to the expected power dissipation in the application environment.

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

This component belongs to the CAT6218 family of LDO regulators from onsemi. The series is designed for general-purpose power management applications requiring compact footprints and efficient linear regulation. The CAT6218 variants typically share similar internal architectures but differ in fixed output voltages and specific package configurations.

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

Direct substitutes include other 3.3 V fixed LDOs in TSOT-23 packages with comparable current ratings, such as the MIC5219 or NCP1117 variants, provided pin compatibility and thermal characteristics align with the design constraints.
