The 78SR105HC is a non-isolated point-of-load (PoL) module from Texas Instruments, designed to deliver a regulated 5V output from a wide input voltage range of 7V to 30V. It is part of the 78SR100 series and offers a maximum output current of 1.5A. The module integrates a switching regulator with internal inductor, short-circuit protection, and over-temperature protection, making it a reliable solution for distributed power architectures.
Key electrical specifications include a typical efficiency of 85%, output voltage tolerance of ±1% typical (±2% maximum), line regulation of ±0.2% typical, and load regulation of ±0.1% typical. The output ripple and noise is 50mVpp typical, and transient response to a 50% load change is 100µs typical. The switching frequency operates between 600kHz and 700kHz.
The device is housed in a 3-SIP (Single In-line Package) module with through-hole, right-angle mounting. Dimensions are 23.9mm (0.94") length, 22.9mm (0.90") width, and 7.9mm (0.31") height, with a weight of 6.5g. It operates over a temperature range of -40°C to 85°C and can be stored from -40°C to 125°C. The thermal resistance (junction to ambient) is 45°C/W with free air convection.
The 78SR105HC is suitable for commercial ITE (Information Technology Equipment) applications. It meets RoHS3 requirements (unverified), MSL level 1, and is REACH unaffected. The part is available for through-hole assembly and is designed for reliable performance in space-constrained power supply designs.
For a 5V output, the input voltage range is 7V to 30V.
