CAT6218-270TDGT3

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

The CAT6218-270TDGT3 is a fixed positive single-output Low Dropout (LDO) voltage regulator manufactured by onsemi. It provides a nominal output voltage of 2.7 V with a maximum dropout voltage of 0.3 V at rated load. The device supports a maximum output current of 300 mA and operates within an input voltage range of 2.3 V to 5.5 V. It is housed in a TSOT-23-5 package, measuring 2.9 mm in length, and is designed for operation across a junction temperature range of -40 °C to +125 °C.

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

Verify the specific suffix 'TDGT3' against official datasheets to confirm package type and tape-and-reel specifications. Ensure the 2.7 V output variant matches system requirements, as this part number family includes multiple fixed voltage options. Confirm RoHS compliance status through manufacturer documentation prior to integration.

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

Select this component when a fixed 2.7 V rail is required with moderate current demands up to 300 mA. The low dropout characteristic makes it suitable for applications where the input voltage may approach the output level. Verify that the thermal performance in the target PCB layout can dissipate heat generated under maximum load conditions.

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

This component belongs to the CAT6218 series of LDO regulators from onsemi. The series is characterized by CMOS technology, offering low quiescent current and high power supply rejection ratios. The CAT6218-270TDGT3 specifically denotes the 2.7 V fixed output version within this lineup, sharing common features like compact packaging and wide input voltage tolerance with other variants.

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. Cross-reference with similar 300 mA LDOs from onsemi or other manufacturers ensuring identical TSOT-23-5 pinout and electrical characteristics.
