TPS72009YZUT

The TPS72009YZUT is a low-current, low-dropout, linear voltage regulator form Texas Instruments. It is designed to support regulated output voltages from 1.25 V to 13.8 V and regulate as low as 0.35 A with a typical dropout of only 150 mV across its entire output voltage range. The integrated fast recovery diode position allows for fast recovery of output current and improved transient response for heavy capacitance loads. The integrated thermal protection prevents the device from damage in case the device is operating above its temperature ratings. The TPS72009YZUT is ideal for applications where low voltage regulation and limited space are primary design considerations.

The key features of the TPS72009YZUT include its low quiescent current, efficient power delivery, and small size. Its typical quiescent current is typically just 0.8 μA, which helps provide efficient and stable power delivery to the output. The low dropout voltage allows the part to deliver its full power output in a small form factor. The TPS72009YZUT is available in an ultra small package, making it an ideal solution for space-constrained applications.

When it comes to performance, the TPS72009YZUT delivers excellent accuracy and load transient response. It is capable of delivering up to ±1% initial accuracy over its output voltage range. The device also offers excellent output load transient response and can drive up to 500 μA of load current without any output voltage ripple. The TPS72009YZUT also offers excellent protection features that include reverse current protection, over-voltage protection, and over-temperature protection.

The TPS72009YZUT is well-suited for a variety of applications, including automotive, audio, test and instrumentation, and industrial control. It is well-suited for use in low-voltage power supplies and low-current driver applications. The device is also ideal for battery-powered applications, such as portable medical devices, wireless sensor nodes, and battery-powered consumer electronics. Its small size and low quiescent current make it an ideal solution for portable applications.

The TPS72009YZUT’s operation involves four basic steps. First, a constant current is supplied to the device’s input. This current is then converted to voltage in the device’s main amplifier stage. The output voltage is thereby generated. Finally, an external series resistor is used to adjust the output voltage. This regulator is designed to maintain a relatively stable output voltage of 1.25 V to 13.8 V regardless of variations in the input voltage.

In summary, the TPS72009YZUT is an excellent linear voltage regulator designed to support regulated output voltages from 1.25 V to 13.8 V. It offers an appealing combination of performance and protection features, such as low quiescent current, low dropout voltage, fast load transient response, reverse current protection, and over-voltage protection. The TPS72009YZUT’s small size makes it an ideal choice for space-constrained designs, and its wide range of applications makes it suitable for a variety of low-voltage power-supply and low-current driver applications.
