TLV1117-25CKVURG3 is a linear voltage regulator released by Texas Instruments. It belongs to PMIC (Power Management IC) family and is classified as Voltage Regulators - Linear. The device provides fixed output voltage of 2.5V and is ideal for applications that require low power consumption, high power supply rejection and low noise regulated power source. It is available in eight package types, making it suitable for a wide range of applications.

Application Field

The TLV1117-25CKVURG3 is ideal for many different types of projects and applications. Some of the applications include:

• Automotive systems
• Portable electronics
• Point of Load Regulation
• Battery powered systems
• USB powered systems
• Industrial logic supplies
• Operational amplifier power supplies

The TLV1117-25CKVURG3 supports a maximum output current of 250mA, making it ideal for a wide range of applications. This device is designed to have a very low quiescent current of only 1µA and a low dropout voltage of 250mV at full load, which significantly increases efficiency and reduces power consumption. Additionally, this device is ideal for low noise regulated power sources, such as in audio applications.

Working Principle

The TLV1117-25CKVURG3 utilizes linear regulators that operate on the principle of negative feedback. The output voltage is regulated by sensing the voltage at the output and comparing it to an internal reference voltage. If the output voltage is too low, the regulator will increase its output current in order to bring the voltage up to the desired level. Conversely, if the output voltage is too high, the regulator will reduce its output current in order to bring the voltage down to the desired level.

The TLV1117-25CKVURG3 uses an external resistor to set the output voltage. This device also features overvoltage protection that cuts off the output voltage if an overvoltage condition is detected. This helps to protect any attached devices from damage due to excessive voltage.

The TLV1117-25CKVURG3 also features thermal shutdown protection, which will shut down the device if the junction temperature exceeds a certain limit. This helps to protect the device from thermal damage.

Furthermore, the TLV1117-25CKVURG3 also includes an input threshold current limit that allows the device to remain in regulation even if the input voltage is very low. This feature helps to ensure that the output voltage remains stable and free from noise even during low input voltage conditions.

Additionally, the device has a low output noise voltage of 0.1μVrms, making it ideal for use in noise sensitive applications. The device also has a minimum PSRR of 80dB at 1KHz and a maximum operating temperature range of -40°C to +85°C.

In summary, the TLV1117-25CKVURG3 is designed to provide a regulated output voltage of 2.5V with low power consumption, high power supply rejection and a low output noise voltage. This device is highly suitable for portable electronics, automotive systems, point of load regulation, industrial logic supplies and more. The device is available in eight package types, making it suitable for a wide range of applications.
