UA78L05CDG4

The UA78L05CDG4, manufactured by ON Semiconductor, is an adjustable low-dropout (LDO) linear voltage regulator. It can be used to regulate the output voltage of various electronic devices and circuits, and is able to do so even with input voltage fluctuations. Given its low dropout voltage, low quiescent current, and wide range of output current, the UA78L05CDG4 is a popular choice for many applications.

The UA78L05CDG4 can be used in a wide range of applications, ranging from computers and cellular phones to automotive and industrial systems. It can also be used to regulate the power supply for microprocessors and digital signal processors (DSPs). It is a popular choice for projects that have low-power and high-accuracy requirements.

The UA78L05CDG4 is designed to be versatile and robust. It features an adjustable output voltage that ranges from 1.2 V to 9 V and a maximum output current of 200 mA. This makes it suitable for powering most low-power applications. It has a low dropout voltage of 0.9 V and a high output voltage accuracy of 0.8%. Moreover, its quiescent current is only 30 µA, so it does not drain much battery power.

The UA78L05CDG4 works by using a feedback system. First, the voltage regulator senses the voltage drop at its output. If the voltage is higher than the desired output voltage, the regulator reduces the output current, causing the voltage to drop. If the voltage is too low, the regulator increases the output current, raising the voltage. This feedback loop keeps the output voltage within a given range, regardless of fluctuations in the input voltage.

The UA78L05CDG4 has a number of other features that make it attractive to designers. These include a wide operating temperature range of −40°C to +125°C and a short-circuit protection system that kicks in when the output current exceeds 200 mA. It also features an overtemperature shutdown and current-limiting protection, and it is provided in a non-inverting TO-252-3 package.

Overall, the UA78L05CDG4 is an excellent choice for applications where low-dropout voltage and high output accuracy are desired. Its low quiescent current, wide operating temperature range, and robust protection system make it a great choice for any project. And because it is designed to be very versatile, the UA78L05CDG4 can meet the needs of many different applications.
