MC7905CD2TR4

MC7905CD2TR4 is an integrated linear voltage regulator which can be used for a wide range of applications. The device is classified as a PMIC – Voltage Regulators – Linear part and it consists of one 8216-pin package. It is designed to work as supply voltage regulator in different situations such as small signal, audio and digital circuits. The peripheral circuitry of the device is minimal and it requires only few external components to get operational.

It is usually used in various applications such as low power consumption systems, PC motherboards and 2.5V, 3.3V and 5V power supply systems. MC7905CD2TR4 is considered to be one of the most cost efficient and reliable voltage regulators available in the market. The on-chip decoupling capacitor reduces output noise and makes the device more stable and immune to EMI.

The working principle of the MC7905CD2TR4 is quite simple. The device has two terminals which are Input and Output. When the voltage applied at the input terminal is too high, the device gets activated and it outputs a voltage lower than the input voltage. The regulator makes use of the Archimedes’s principle for power conversion. It converts the input voltage into a higher current which is then regulated and outputted as a lower voltage to the load.

The input range of the device is from 1.5 V to 37V while the output range is from 0V up to 1.231V. The operating temperature range of the device is from -40°C to 125°C. The device itself dissipates 10mW maximum of power, which means its power consumption is very low. It also has a very low dropout voltage, which is just a few tens of mV.

The device uses built-in voltage reference, protection and filtering circuits, which makes it very effective and efficient. The built-in self-protection feature ensures safe and reliable operation of the regulator. The output voltage is also quite accurate and stable with a very low output voltage ripple. The monolithic structure of the device also provides excellent temperature stability and long-term stability.

In addition, the device has a high efficient switching frequency which makes it more suitable for high power applications. The MC7905CD2TR4 also provides fast transient response to voltage and current changes. It also has an embedded current limit protection which helps in protecting the board from over-current situation.

Overall, MC7905CD2TR4 is an excellent voltage regulator with suitable features for a wide range of applications. Its low power consumption, high accuracy and excellent ripple rejection make this device quite popular in the market. Its on-chip decoupling capacitors and current limit protection make it a very reliable and safe device for a variety of applications.
