UA78L12ACLPR is a linear voltage regulator from Texas Instruments. It is suitable for post-regulation in off-line applications where space is at a premium. It has versatile boundary conditions, ranging from a common programming range, allowing a wide range of operating conditions to be achieved. The voltage regulation performance is also excellent, with a maximum output voltage change of only 0.1% accuracy over an input voltage range of 3.3V to 32V.

Designers need a power scalable design, allowing the UA78L12ACLPR’s low quiescent current and high current capabilities to be used in a wide range of applications. The output voltage of the regulator, which can range from 3V to 32V, can be adjusted using the regulator’s external control circuitry. Its high output current capability allows for post-regulation of high power applications. This regulator also features an internal thermal shutdown circuit, which ensures the device does not overheat if the external load current is set too high.

The UA78L12ACLPR Linear Voltage Regulator has a wide selection of applications. In battery powered systems, it can be used to supply a regulated voltage to microcontrollers, or any other application with highly precise voltage requirements. It is also suitable for use in applications that require low noise and low ripple, such as audio amplifiers and television receivers. In addition, this regulator can be used to provide a regulated output voltage in a DC/DC converter, saving power by maximizing the efficiency of the converter.

The working principle of the UA78L12ACLPR voltage regulator involves a series of components, including a zener diode, a resistor, and an error amplifier. The zener diode acts as a reference, maintaining the output voltage at a specified level. The resistor and the error amplifier form a feedback loop, ensuring that the output remains stable. The output voltage is then compared to the reference voltage and adjusted accordingly.

The UA78L12ACLPR is a cost-effective, reliable and efficient linear voltage regulator, that can be used in applications requiring precise voltage regulation. Its wide range of boundary conditions, along with its excellent voltage regulation performance and low quiescent current, make it a suitable choice for many applications. Its internal thermal protection circuit and its ability to be used in high power applications also make it an attractive option.
