CAT6221-PGTD-GT3 is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists onsemi. Its product description is IC REG LIN 3V/1.8V 300MA TSOT23. Review the specifications below when checking this part for your BOM.
The CAT6221-PGTD-GT3 is a dual-output low-dropout (LDO) linear voltage regulator manufactured by onsemi. It provides fixed output voltages of 3.0V and 1.8V with a maximum output current of 300mA per channel. The device operates within an input voltage range of 2.3V to 5.5V and features a typical quiescent current of 160µA. It is housed in a TSOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +125°C.
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix GT3 corresponds to the required reel packaging configuration. Ensure compatibility with existing thermal management designs given the small form factor. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans.
Select this component when dual fixed outputs are required without external feedback resistors. The 300mA current rating suits moderate load applications. Verify that the input voltage remains within the specified 2.3V to 5.5V window. Consider the thermal dissipation capabilities inherent to the TSOT-23-6 package under maximum load conditions.
This part belongs to the CAT6221 series of dual LDO regulators from onsemi. It is designed for space-constrained applications requiring two distinct regulated voltages from a single source. The series emphasizes low noise and high power supply rejection ratio characteristics suitable for sensitive analog and digital circuits.
CAT6221-MPTD-GT3 offers similar dual output functionality with different voltage configurations.
