Introducing the ST1S14PHR

As a manufacturer located in China, we are proud to introduce our latest product, the ST1S14PHR. This high-performance, low dropout voltage regulator can help merchants across the world to optimize and enhance their electronic designs. If you are looking for a reliable and high-quality voltage regulator that can deliver outstanding performance and efficiency, look no further than the ST1S14PHR.

The ST1S14PHR is a high performance, synchronous step-down regulator that is capable of delivering up to 1.5A of output current with a maximum input voltage of 18V. This device is based on a fixed frequency, pulse-width modulated (PWM) voltage mode control scheme, which allows for excellent transient response and easy loop compensation. The device also features an adjustable soft-start function that allows for extended lifespan of the device and protection of the downstream circuits from voltage overshoots at start-up.

The device boasts an ultra-low dropout voltage of only 150mV at full load, which makes it ideal for use in applications where the input and output voltages are very close. This feature is particularly useful in situations where the input voltage may be unstable or where the input voltage is supplied by a battery that is in the process of discharging.

The ST1S14PHR offers excellent load regulation capabilities, with a typical load regulation of only 0.5% over the entire operating temperature range. Furthermore, the device has a very low output voltage ripple, making it suitable for use in applications where a low noise output voltage is required.

One of the key benefits of the ST1S14PHR is its high efficiency. The device features a peak efficiency of up to 93%, which helps to reduce power dissipation and extend the lifespan of the device. This high efficiency is achieved through the use of a synchronous rectification scheme, which eliminates the need for an external diode and reduces the overall size and cost of the device.

The device has a built-in overcurrent protection function, which helps to prevent damage to the device and downstream circuits in case of overloads or short circuits. The device also has a thermal shutdown function, which disables the device in case of overtemperature conditions, preventing the device from being damaged and increasing the reliability of the device.

The ST1S14PHR is designed to be easy to use and integrate into a variety of electronic designs. It requires only a few external components and has a small form factor, which makes it a great choice for use in space-constrained applications. The device also has a shutdown mode function, which helps to reduce standby power consumption and extend the battery life in portable devices.

Overall, the ST1S14PHR is an excellent choice for merchants looking for a reliable and high-performance voltage regulator for their electronic designs. With its high efficiency, low dropout voltage, and excellent load regulation capabilities, the device can help to optimize and enhance your designs, while the built-in overcurrent protection and thermal shutdown functions provide added safety and reliability. If you are looking for a voltage regulator that delivers outstanding performance and efficiency, look no further than the ST1S14PHR.

Description

The ST1S14 is a step-down monolithic power switching regulator able to deliver up to 3 A DC current to the load depending on the application conditions. The high current level is also achieved thanks to a HSOP8 package with exposed frame, that allows to reduce the Rth(JA) down to approximately 40 °C/W. The output voltage can be set from 1.22 V. The device uses an internal Nchannel DMOS transistor (with a typical RDS(on) of 200 mΩ) as the switching element to minimize the size of the external components. The internal oscillator fixes the switching frequency at 850 kHz. Power good open collector output validates 

the regulated output voltage as soon as it reaches the regulation. Pulse-by-pulse current limit offers an effective constant current short-circuit protection. Current foldback decreases overstress in a persistent short-circuit condition.
