The integrated circuit UA78L08CDE4 is a linear, low-dropout, positive voltage regulator. It is designed to provide a stable 8V output voltage from a wide input voltage range (4.6V - 20V). The IC is available in two versions; with and without the enable pin. The main purpose of the UA78L08CDE4 is to provide a low-noise voltage output from the fluctuating input voltage. This stability is achieved through the use of advanced regulation circuitry, which maintains the output voltage within a narrow tolerance range, regardless of the input voltage level.
The main components of the UA78L08CDE4 are a voltage reference, an adjustable threshold comparator, a current sense amplifier, and a series regulator. The voltage reference provides a reference voltage of 8V which is compared against the input voltage by means of the adjustable threshold comparator. If the input voltage is higher than 8V then the comparator raises an output flag, indicating that the output voltage needs to be regulated. The current regulator is then switched on to reduce the output voltage. Conversely, if the input voltage is less than 8V, then the output flag is lowered, signaling the current regulator to increase the output voltage.
The UA78L08CDE4 features overload protection, under voltage lockout, and reverse current protection. The device also has a built-in thermal shutdown, which limits the peak temperature of the IC during overload conditions. Furthermore, the device has current foldback protection, which prevents overstressing the output voltage regulator in the event of a current overload. The high current limitation feature protects the device from excessive current and short-circuit conditions.
The UA78L08CDE4 is available in a wide range of packages, providing customization options for different applications. The typical application areas for the device include automotive systems, industrial controllers, consumer electronics, and telecom equipment. The device can also be used in power supplies, medical equipment, robots, and most other systems requiring a stable 8V output.
In summary, the UA78L08CDE4 is a high-performance, low-dropout voltage regulator designed to provide a stable 8V output voltage from a wide range of input voltage levels. The device features protection against overload and short-circuit conditions, making it ideal for use in a wide range of applications. It is available in a variety of packages, making it easy to customize the device to the specific requirements of the system.
