PMIC products are widely used in many fields. Among them, voltage regulators are one of the most widely used types. UA78L10ACDRE4, a linear voltage regulator, is one such device. This article will explain the application field and working principle of UA78L10ACDRE4.

UA78L10ACDRE4 is a fixed 3-terminal +10V linear voltage regulator with overload protection and output ON/OFF control functions. Because of its high precision, small size, and low input voltage, UA78L10ACDRE4 is strongly suitable for hand-held applications. It can provide a regulated +10V output voltage from 3V~18V, so it is mainly used in portable electronic devices such as mobile phones, PDAs, and digital cameras.

UA78L10ACDRE4 works on the principle of direct power conversion. A zener diode, which is the core component of the IC, uses the voltage difference between the input and output terminals to generate a constant voltage output. The zener diode is connected in series with the emitter-base junction of the transistor. The transistor then controls the current output and regulates the output voltage.

The primary component of this voltage regulator is a PMOS transistor. This transistor provides a high-impedance feedback path that allows the output voltage to be accurately regulated. The output voltage is also protected from overcurrent and overvoltage conditions. In addition, the UA78L10ACDRE4 also has shutdown and enable control pins to provide remote output ON/OFF functions.

In conclusion, UA78L10ACDRE4 is a high-performance linear voltage regulator. Its small physical size and low input voltage make it ideal for portable applications. Its direct power conversion principle ensures a stable and accurate output voltage. Its overload protection and enable/shutdown functions make it suitable for use in a variety of applications.
