The TPS736125DRBTG4 from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator that offers a very low dropout voltage and low quiescent current. This regulator is part of the TPS736xx family and is designed to provide a regulated output of 1.25V with an input voltage range from 1.7V to 5.5V. It is capable of delivering up to 400mA of continuous output current, making it suitable for a wide range of applications including portable and battery-powered devices.

Key Features:

• Low Dropout: The device provides excellent regulation with a very low dropout voltage, typically just 250mV at full load, which is ideal for applications with a tight voltage supply margin.
• High Accuracy: Output voltage accuracy is maintained within a tight range, with a typical accuracy of 1% over the entire temperature range.
• Low Quiescent Current: The TPS736125DRBTG4 is optimized for low standby power consumption, with a typical quiescent current of only 60µA, which is crucial for extending battery life in portable applications.
• Thermal Shutdown and Overcurrent Protection: These built-in safety features ensure that the device and your application are protected from excessive heat and load conditions.
• Adjustable Output: While the device comes with a fixed 1.25V output, it also supports adjustable output voltages from 1.2V to 5.5V with the use of external resistors, providing design flexibility.

Package and Reliability:

The TPS736125DRBTG4 is offered in a compact 3.00 mm x 3.00 mm SON-8 package, which is ideal for space-constrained applications. The device is characterized for operation from –40°C to 125°C, ensuring reliable performance across a wide range of environmental conditions.
