TPS77030DBVR

The TPS77030DBVR is a 300 mA low drop-out (LDO) linear voltage regulator that is designed for use in applications such as LCD backlight power supplies, laptop power supplies, as well as other applications that require low output voltage levels. The TPS77030DBVR is capable of providing up to 300mA of output current with a low quiescent current of only 500 µA, making it ideal for low voltage, low power battery applications. The adjustable output voltage range of 1.2V to 3.3V provides flexibility for supporting a wide range of devices.

In order for the TPS77030DBVR to regulate performance, the total operating current should not exceed 300mA, including the output current and any additional current supplied through an external resistor. The output voltage is regulated by connecting a voltage divider across the FB and GND pins, with a 100K resistor from FB to GND, and an adjustable resistor between FB and VOUT. The output voltage can then be adjusted by changing the resistance in the voltage divider.

The TPS77030DBVR is protected from overvoltage, overcurrent and overtemperature conditions, ensuring safe and reliable operation. The device also includes external shutdown control to enable/disable the output voltage and current. The TPS77030DBVR provides a low output voltage ripple, and is capable of driving large capacitive loads with no additional filtering or compensation.

The TPS77030DBVR is also capable of operating in a wide range of temperatures. It is rated to withstand ambient temperatures from -40°C to +85°C and is qualified for operation with a maximum junction temperature of +125°C. The device is available in the space saving SOIC-8 package, and operates from a 4.5V to 18V input voltage range.

Overall, the TPS77030DBVR is an excellent choice for applications that require low output voltage levels and low quiescent currents, such as LCD backlight power supplies and laptop power supplies. Its adjustable output voltage range of 1.2V to 3.3V provides great flexibility for powering a wide range of devices, and the device includes protection mechanisms to ensure safe, reliable operation.
