Texas Instruments TPS74401KTWT is a positive adjustable linear voltage regulator capable of delivering up to 3A output current. This device features a low dropout voltage of 0.24V at 3A, ensuring efficient operation even under heavy load conditions. The adjustable output voltage can be set from 0.8V to a maximum of 3.6V, with an input voltage range up to 5.5V. Control features include an Enable pin, a Power Good output, and a Soft Start function for controlled power-up sequences. Protection mechanisms are integrated to safeguard the device and the load, encompassing Over Current, Over Temperature, Short Circuit, and Under Voltage Lockout (UVLO). The TPS74401KTWT is supplied in a TO-263-8 (D2PAK-7) surface-mount package, commonly used in power management applications across automotive, industrial, and base station infrastructure sectors. The device exhibits a high Power Supply Rejection Ratio (PSRR) ranging from 73dB to 50dB over the frequency band of 1kHz to 800kHz, making it suitable for noise-sensitive power delivery.
