Linear & Switching Voltage Regulators

TPS79927DRVR Description

The TPS79927DRVR from Texas Instruments is a high-performance linear regulator designed to deliver a fixed output voltage of 2.7V with a maximum output current of 020mA. This device is optimized for low dropout voltage, ensuring efficient power conversion even at low input voltages. The maximum input voltage is rated at 6.5V, making it suitable for a wide range of applications where input voltage fluctuations are common.

The regulator features a low dropout voltage of 0.18V at 200mA, which is significantly lower than many competing regulators. This low dropout voltage ensures that the regulator can maintain its output voltage even when the input voltage is close to the output voltage, thereby improving overall efficiency and reducing power loss.
