CAT6218-285TDGT3

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

The CAT6218-285TDGT3 is a fixed positive single-output Low Dropout (LDO) voltage regulator manufactured by onsemi. It provides a nominal output voltage of 2.85 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 is housed in a TSOT-23-5 surface-mount package, measuring 2.9 mm in length and 1 mm in height. The component operates within a junction temperature range of -40 °C to +125 °C and complies with RoHS standards.

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

Verify the specific suffix 'TDGT3' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the part number matches the exact output voltage variant required for the design. Cross-reference with authorized distributors to confirm current availability status and lead times. Check for any recent product change notifications or end-of-life notices associated with this specific revision.

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

Select this component when a stable 2.85 V rail is needed with moderate current demands up to 300 mA. The low dropout characteristic makes it suitable for applications where the input voltage is close to the desired output level. Consider the thermal performance in the TSOT-23 package relative to the expected ambient temperature and load conditions. Verify that the input voltage does not exceed the maximum rating of 5.5 V.

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

This LDO regulator belongs to the CAT6218 series from onsemi, designed for efficient power management in space-constrained applications. The series offers various fixed output voltages to support different logic families and sensor requirements. The TSOT-23-5 package allows for high-density PCB layouts while maintaining reliable thermal dissipation for continuous operation in consumer and industrial electronics.

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

Direct substitutes include other CAT6218 variants with different fixed output voltages if the voltage requirement changes, such as CAT6218-180TDGT3 for 1.8 V. For similar performance characteristics, consider the CAT6217 series, which offers comparable dropout voltages but may differ in output current capabilities. Always verify pinout compatibility and electrical parameters before substitution.
