TPS72615KTTR

The Texas Instruments TPS72615KTTR is a 1-A low-dropout (LDO) linear regulator with fixed voltage options, commonly used for powering DSPs, FPGAs, and microcontrollers. It includes integrated supervisory circuitry that provides an active low RESET signal when the output falls out of regulation. This regulator supports input voltages down to 1.8V and offers a low dropout voltage of 170mV at 1A. The device is stable with any type or value of output capacitor, allowing for tailored output transient performance.

Key electrical characteristics include a typical ground current of 210 µA at full load, dropping to less than 80 µA at no load, and a standby current of less than 1 µA. It operates over a wide input voltage range of 1.8V to 6V and maintains ±2% output voltage tolerance over line, load, and temperature variations from -40°C to +125°C. The regulator also features integrated UVLO with thermal and overcurrent protection.

Designed for applications such as PCI cards, modem banks, telecom boards, and DSP/FPGA power supplies, the TPS72615KTTR is available in a 5-lead DDPAK/TO-263-5 surface-mount package. The tab on this package is connected to GND. Its low noise capability, high current operation, and ease of power dissipation make it suitable for noise-sensitive applications.
