• High Output Voltage Accuracy: ±1.5%
• Disable control: Shuts Device Down When Pin Is Low
• Wide Temperature Range: -40 to 125°C

Working Principle

The TPS71733DCKTG4 voltage regulator is a linear regulator, which means it works by converting the input voltage to a lower output voltage using a series of resistors and capacitors. This is a simple and efficient way to reduce the voltage without introducing any noise or ripple into the output. The device operates by using a control loop to compare the output voltage to a reference voltage. If the output voltage is too high, the control loop will reduce the output current to lower the output voltage. If the output voltage is too low, the control loop will increase the output current to bring the voltage back up.

Conclusion

The TPS71733DCKTG4 from Texas Instruments is a low-power, high-accuracy voltage regulator suitable for a wide range of applications. It offers excellent quiescent current and low dropout voltage for ultra-low power applications, and features a 1 MHz minimum switch frequency. The device is also compliant with the JEDEC JESD47 standard and operates over a -40 °C to +125 °C temperature range. Additionally, the device can automatically transition into shutdown mode when the input voltage is below the output voltage.
