The 78ST105HC is a non-isolated point-of-load (PoL) module from Texas Instruments, part of the 78ST100 series. It provides a regulated 5V output at up to 1.5A from a wide 7V to 30V input range. The module integrates the switching regulator and inductor, offering a compact solution for board-mounted power conversion.
Key electrical specifications include a typical efficiency of 85% at Vin=10V and Io=1A, a switching frequency of 650kHz typical, and line and load regulation of ±0.2% and ±0.1% typical respectively. Output voltage tolerance is ±1.0% typical, and ripple/noise is 65mVpp typical at Vin=9V and Io=1.5A. The module includes over-temperature and short-circuit protection.
The 78ST105HC comes in a 3-SIP package with through-hole, right-angle mounting. It measures 23.9mm x 22.9mm x 7.9mm and weighs 6.5g. An external 100µF electrolytic or tantalum output capacitor is required for proper operation, while a 1µF ceramic input capacitor is optional.
This module is suitable for commercial ITE applications where a compact, efficient step-down conversion from a wide input voltage is needed.
The output voltage is 5V nominal and the maximum output current is 1.5A.
The input voltage range is 7V minimum to 30V maximum.
The operating temperature range is -40°C to 85°C.
It comes in a 3-SIP module package with through-hole, right-angle mounting.
The RoHS status is listed as RoHS3 compliant, but this is unverified.
The typical efficiency is 85% at Vin=10V and Io=1A.
It includes over-temperature protection (OTP) and short-circuit protection (SCP).
