PMIC (Power Management Integrated Circuits) form an integral part of modern power electronics design. Specially designed PMIC Voltage regulators provide steady output voltages for powering various electrical systems, regardless of input voltage. Linear voltage regulators are one of the simplest and most reliable forms of voltage regulation available. The UA7815CKTER is a monolithic linear voltage regulator from Texas Instruments, offering complete output voltage flexibility through its adjustable output capabilities.

The UA7815CKTER is a three-terminal negative adjustable voltage regulator, able to provide up to 15V of output voltage when supplied with appropriate input voltage. The output voltage range is from -1.2 V to -15 V and the device requires only two external resistors to set the desired output voltage. Its maximum output current is 1A, and the dropout voltage at 1A is typically 1.2V. The device is designed to provide a regulated negative output and sink current up to 1A.

The UA7815CKTER regulator is a versatile, ultra-low-noise and low-input voltage device that can be used in a wide range of applications such as in laptops and desktops, automotive systems, battery chargers, industrial control systems and other power-sensitive portable devices. It is designed to provide a low-noise power supply with a stable, low-dropout output voltage, therefore making it ideal for powering sensitive analog circuitry in microprocessor-based systems.

The UA7815CKTER works on a principle of series voltage regulation. It maintains a desired output voltage by drawing a varying load current via a series-regulated element, and thereby controlling the amount of current flowing through the load. As the input voltage changes, the output voltage remains constant. When the input voltage goes above the threshold voltage and exceeds the load voltage, theseries regulator will draw current from the load, thus ensuring that the output voltage remains constant.

The UA7815CKTER Voltage Regulator also provides a great deal of protection against over-voltage and over-current conditions, as well as protection against excessive power dissipation. It is designed to stand off input voltages up to 40V and can handle short circuit currents up to 1A. The Thermal protection circuit limits the junction temperature to protect the device against overheating.

The UA7815CKTER is a great choice for applications that require high efficiency and stability, low noise and dropout voltages, plus protection against overload. Its three-terminal adjustable output voltage and ability to sink 1A of current make it ideal for many applications in power electronics design. It is an ideal choice for designers looking for an adjustable voltage regulator that can provide high efficiency and stability along with low noise and dropout levels.
