( Brand: Texas Instruments ), ( Manufacturer Part Number: PT78ST115H ), ( Part Type: Regulator )
The PT78ST115H Texas Regulator is a high-quality voltage regulator designed to provide a stable 15V output with a maximum current of 1.5A. This regulator is ideal for various applications that require a steady power supply, such as electronic devices, battery-powered systems, and test equipment.
The PT78ST115H is a linear voltage regulator, which means it uses an external series pass transistor to regulate the output voltage. This design ensures a very low noise output, making it suitable for applications where noise-sensitive components are used. The regulator has a wide input voltage range of 7V to 35V, allowing it to operate from a wide variety of power sources.
The regulator features a thermal shutdown function, which protects it from overheating by automatically disconnecting the output when the internal temperature exceeds a safe limit. It also has a built-in over-current protection feature, which limits the output current to 1.5A to prevent damage to the regulator or connected components.
The PT78ST115H is a horizontal regulator, which means it can be mounted horizontally or vertically on a PCB. It has a compact size of 11.5mm x 7.8mm, making it easy to incorporate into small electronic designs. The regulator also has a low quiescent current of 2mA, which helps to reduce power consumption and prolong battery life in battery-powered applications.
The PT78ST115H Texas Regulator is a reliable and versatile voltage regulator that offers excellent performance and protection features. Its wide input voltage range, low noise output, and thermal and over-current protection make it an excellent choice for a wide range of applications.
The Texas Instruments PT78ST115H is a linear voltage regulator that outputs 15V at a current of 1.5A. Here are some pros and cons of buying this regulator:
