The TPS79901YZUT is a low-dropout (LDO) linear voltage regulator from Texas Instruments designed to deliver outstanding performance in a compact package. This highly efficient regulator offers a low quiescent current, making it an ideal choice for battery-powered and low-power applications. The device is capable of sourcing up to 200 mA of output current, which is suitable for a variety of electronic devices.

Key Features:

• High Accuracy: The TPS79901YZUT provides excellent regulation with an accuracy of 2% over temperature, line, and load variations, ensuring a reliable power supply for sensitive components.
• Low Dropout Voltage: With a typical dropout voltage of only 40 mV at a 200 mA load, this LDO helps maintain regulation even when the supply voltage is close to the output voltage, maximizing battery life.
• Low Quiescent Current: The device features a low quiescent current of 40 µA during operation and 1 µA in shutdown mode, significantly reducing power consumption when in idle or standby states.
• Adjustable Output: It offers an adjustable output voltage range from 1.2 V to 6.5 V, providing flexibility to power a wide range of circuits and components.
• Thermal Protection: The TPS79901YZUT includes over-temperature protection, which safeguards the device and the application from thermal damage.
• Stable with Low ESR Capacitors: The regulator is stable with ceramic capacitors, which have a low equivalent series resistance (ESR), reducing the size and cost of the external components required.
