The Texas Instruments PT78ST112V is a 1.5 Amp positive step-down integrated switching regulator from the PT78ST100 series. This device features a very small footprint, high efficiency greater than 85%, and a self-contained inductor. It provides excellent line and load regulation with internal short-circuit and over-temperature protection.
Key electrical specifications include an output current of up to 1.5A and a typical output voltage of 12V. The input voltage range varies depending on the output voltage, for example, 9V to 38V for a 5V output. Efficiency is rated up to 90% under specific conditions. The switching frequency operates around 650kHz.
Designed for ITE (Commercial) applications, the PT78ST112V is housed in a 3-SIP Module package and features a Through Hole mounting type. The operating temperature range is -40°C to 85°C, with recommended operating temperatures slightly lower under free air convection. It also includes features like Over-Temperature Protection (OTP) and Short-Circuit Protection (SCP).
External components include an optional 1µF ceramic capacitor (C1) and a required 100µF electrolytic capacitor (C2) for proper operation. The datasheet provides detailed ordering information for various output voltages and package suffixes.
