LP5907UV-2.8EVM/NOPB

The LP5907UV-2.8EVM/NOPB is an Evaluation board featuring an adjustable low quiescent current linear regulator from Texas Instruments, specifically designed for the LP5907 linear voltage regulator. It provides unique features such as adjustable output voltage, adjustable quiescent current, and output current rating up to 0.8A. With its low quiescent current, the device can enable longer battery life for end applications powered by batteries or USB.

LP5907UV-2.8EVM/NOPB is an Evaluation board from the Linear Voltage Regulators category of devices from Texas Instruments. It’s a 4-pin SOT-223 package buried zener diode voltage regulator, with adjustable output voltage and adjustable quiescent current down to 20 uA. It also offers protection against both short circuit and over current conditions by utilizing a proprietary on-chip voltage monitoring circuit.

The LP5907UV-2.8EVM/NOPB linear voltage regulator has a wide range of applications. It can be used to reduce noise, stabilize voltage levels, and to regulate battery voltage in low power systems. It is used in applications such as automotive, industrial, and consumer machines as well as for portable gaming consoles, smartphones, and wearable electronics. The LP5907UV-2.8EVM/NOPB can also be used for noise isolation in applications where the input voltage fluctuates.

The operation of the LP5907UV-2.8EVM/NOPB is based on the Volterra Series regulator principle. The device has two stages — the first stage is a linear regulator which operates as long as the output voltage remains constant or slightly higher than the reference voltage. The second stage is composed of two transistors, in a configuration known as a cascode, which switches to regulate the output voltage if it drops below the reference voltage. The cascode transistors significantly reduce power dissipation in the voltage regulator and also guarantee a low output impedance which minimizes output voltage noise.

The LP5907UV-2.8EVM/NOPB is an efficient device for maintaining a steady voltage output in low power applications. It offers features such as adjustable output voltage, low quiescent current, and output current rating up to 0.8A, making it appropriate for a variety of applications.
