FAN5236QSC Application and Working Principle

The FAN5236QSC is a dual-channel, low-dropout (LDO) linear regulator derived from the popular Fairchild FAN5236 family of products. The FAN5236QSC is a positive, dual-channel, low-dropout (LDO) voltage regulator specifically designed for power management applications requiring multiple output voltages and tight regulation performance.Operating from a 4.5 V to 15 V input voltage, the FAN5236QSC delivers two adjustable, low-dropout linear-regulated output voltages. The outputs can be independently adjusted up to the input voltage with a 1% accuracy between 4.5 V and 30 V and 5% tolerance from 30 V to 60 V, enabling efficient design and making the part an ideal solution for applications requiring multiple tight regulated outputs. The FAN5236QSC has an input voltage range of 4.5 V to 15 V and an output voltage range of 0.8 V to 60 V. It offers tight regulation performance of ±1% with a power output capability of up to 1.2 A. Its low dropout voltage and fast start up capability make the FAN5236QSC an ideal solution for power management applications in both automotive and consumer applications.The FAN5236QSC has a quiescent current of just 6.6 mA and a low dropout voltage of 0.2 V. It has an internal thermal shutdown protection and also includes over-current protection, over-temperature protection, short-circuit protection and reverse load protection features. In addition to this, the device provides transient over voltage protection during current surge when powering up the regulator.The FAN5236QSC offers a wide range of features such as low dropout voltage and tight regulation performance. It can be used for power management in cell phones, portable digital media players, PDAs, cameras, and automotive applications. Its compact size, low power consumption and versatility make it an ideal solution for many applications requiring multiple output voltages.FAN5236QSC Working PrincipleThe FAN5236QSC is a dual-channel, low-dropout (LDO) linear regulator derived from the popular Fairchild FAN5236 family of LDO regulators. This regulator is based on an the error amplification principle. It consists of an error amplifier, a linear regulator and multiple pass transistors connected in an ouput configuration.The error amplifier continuously monitors the output voltage of the regulator and compares it with a reference voltage. Once the output voltage deviates from the required value, a correction signal is generated by the error amplifier and sent to the linear regulator to correct the output voltage. The linear regulator then amplifies this signal and it is passed on to the pass transistors which then adjust the output voltage accordingly.The FAN5236QSC is equipped with advanced features such as short-circuit protection, over-temperature protection, over-current protection and reverse load protection. Also, the device can provide transient over voltage protection during current surge when powering up the regulator.In conclusion, the FAN5236QSC is a cost-effective, dual-channel, low-dropout (LDO) linear regulator that is ideal for a wide range of applications requiring multiple output voltages and tight regulation performance. It is easy to use and offers features like short-circuit protection and over-temperature protection. Its low dropout voltage, fast start-up capability, low quiescent current and wide input voltage range make it an ideal solution for power management in automotive and consumer applications.
