CAT6221-MGTD-GT3

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

The CAT6221-MGTD-GT3 is a dual-channel low dropout (LDO) linear voltage regulator manufactured by onsemi. It integrates two positive fixed-output regulators in a single TSOT-23-6 package, providing 300 mA per channel with output voltages of 2.8 V and 1.8 V. The device features a maximum input voltage range up to 5.5 V and operates within an extended temperature range of -40°C to +125°C. Key electrical specifications include a typical dropout voltage of 0.35 V at full load current and a quiescent current of 160 µA. Each regulator includes an independent enable pin for power management control.
