78L05A Voltage Regulator IC description
78L05A is a fixed voltage (5V) coordinated controller, which can be applied to numerous applications. It’s phenomenal interior present and warm shutdown attributes make it particularly reasonable for over-burden. When it is utilized to supplant the customary Zener diode obstruction gathering, its yield impedance is improved adequately, however the predisposition current is incredibly decreased.
In another words,78L05A arrangement is a fixed voltage (5V) eight terminal coordinated voltage controller, which is appropriate for some applications. Like a solitary point voltage controller which needs to restrict the clamor and take care of the conveyance issue, it can likewise be utilized with other power move gadgets to frame a steady voltage power supply with huge current, for example, a steady yield current of up to 100mA.
78L05A specifications and features
● 5V Positive Voltage Regulator
● Input voltage up to 30-35V
● Maximum Input Voltage is 30V
● Operating current (IQ) is 5mA
● Protection from Internal Thermal Overload and Short circuit current limiting is available.
● Output current can reach 100mA
● No external connector
● Internal thermal overload protection
● Internal short circuit current limit
● From the end of 2004, all types of packaging were lead-free packaging products
Working principle of 78L05A
Voltage controllers are regular in electronic circuits. They give a steady yield voltage to a fluctuated information voltage. For our situation the 78L05A IC is a notable controller IC that discovers its application in a large portion of the tasks. The name 78L05A connotes two meaning, “78” means that it is a positive voltage controller and “05” means that it gives 5V as yield. So, our 7805A will give a +5V yield voltage. The yield current of this IC can go up to 100mA. Yet, the IC experiences substantial warmth misfortune thus a Heat sink is suggested for ventures that devour progressively current. For instance, if the info voltage is 12V and you are expending 50mA, then (12-5) * (50*10^-3) = 0.35W. This 0.35 Watts will be dispersed as heat.
Another prominent voltage controller is 7805A which is bulkier in size yet has high current rating of about 1A. Along these lines, on the off chance that you are searching for a littler bundle of voltage controller that has little flow rating in TO-92 bundle then this IC may be the correct decision.
Application of 78L05A
7805A IC is used in a wide range of circuits. The major ones are as below.
● Fixed-Output Regulator
● Positive Regulator in Negative Configuration
● Adjustable Output Regulator
● Current Regulator
● Adjustable DC Voltage Regulator
● Regulated Dual-Supply
● Output Polarity-Reversal-Protection Circuit
● Reverse bias projection Circuit
7805A IC also finds usage in building circuits for inductance meter, phone charger, portable CD player, infrared remote-control extension and UPS power supply circuits.
