The TPS78401DBVR from Texas Instruments is a high-performance linear voltage regulator designed for efficient power management. It delivers up to 300mA of output current with a low quiescent current of 25µA typical, making it suitable for battery-powered applications.
This LDO regulator features a high Power Supply Rejection Ratio (PSRR) of 49dB at 100KHz, ensuring clean power delivery even in noisy environments. The adjustable output voltage can be set between 1.2V and 5.5V, with a maximum input voltage of 6V. Key electrical specifications include a typical accuracy of 0.75% and an ultra-low dropout voltage of 115mV at 300mA.
Designed for ease of use, the TPS78401DBVR includes an Enable pin for control and protection features such as over current, over temperature, and UVLO. It also incorporates an internal soft-start time of 350µs to minimize inrush current. The device is housed in a compact 5-pin SOT-23-5 package, suitable for surface mounting in space-constrained designs.
Operating across a wide temperature range of -40°C to 125°C, this voltage regulator is a reliable choice for various electronic systems requiring stable and efficient voltage regulation.
