SR3100-HF

What is SR3100-HF?

The SR3100-HF is an integrated circuit (IC) manufactured by Texas Instruments. It is a linear voltage regulator that provides a regulated output voltage of up to +10.5V with a maximum output current of 100mA. It is designed for use in low-power applications such as portable electronics and battery-powered devices. The SR3100-HF is capable of operating from input voltages ranging from 3.2V to 10.5V, and its low quiescent current makes it ideal for use in battery-powered applications. It also features an enable/disable pin which can be used to turn the device on and off, and it has built-in thermal and current-limit protection. The SR3100-HF is available in a small, 8-pin DIP package, making it suitable for use in tight-space applications.

How to use SR3100-HF?

The SR3100-HF is a simple voltage regulator IC, and as such is easy to use. To set up the device, all that is needed is an input voltage between 3.2V and 10.5V, a load, and a ground connection. A single resistor and capacitor can be connected to the output pin to create a low-pass filter, which can reduce output ripple. Once the device is connected, the EN/DIS pin can be used to turn the device on and off. The output voltage can be adjusted by connecting a voltage divider to the ADJ pin. Finally, the device should be mounted to a heatsink to ensure proper thermal performance.

Overall, the SR3100-HF is a simple yet effective voltage regulator IC, and is suitable for a variety of low-power applications.
