PMIC - Voltage Regulators - Linear

Voltage regulator is an important voltage management device used in electronic systems to supply and adjust the steady and balanced power required in electronic applications.The S-13R1D12-I4T1U3 series is a kind of PMIC - Voltage Regulators - Linear.This article is discussing its application fields and working principles.

Application Fields of S-13R1D12-I4T1U3 Series

The S-13R1D12-I4T1U3 series is a family of low dropout regulators integrated with two selectable current limiting mechanisms and adjustable voltage settings with an external control voltage.It has wide application fields,such as it can be used in car media systems,cell phones,smart phones,mobile devices,internet access and so on.Due to their advantages of low dropout voltage and wide voltage range, they are also widely used in portable electronic devices.It is also used to regulate the negative voltage of the communication interface circuit and other negative voltage supply circuits.

Working Principle of S-13R1D12-I4T1U3 Series

The core of S-13R1D12-I4T1U3 is the MOSFET pass transistor, which can adjust the voltage to a predetermined level by the feedback signal from the external voltage reference voltage.When the input voltage is lower than the output voltage, the pass transistor is turned on, and the current is directly passed to the load.When the input voltage is higher than the output voltage, the transistor is turned off, and the current is diverted to the ground, thus maintaining the output voltage at a certain level.The S-13R1D12-I4T1U3 has two over current protection mechanisms which are foldback current limiting and dual-source current limit, they can protect the load devices from the damage of large currents,also protecting the power supply circuit.The internal devices all have over-temperature protection, which can effectively prevent the device from being damaged by high temperature.To sum up, S-13R1D12-I4T1U3 series is an excellent PMIC - Voltage Regulators - Linear with wide application fields for providing lasting and stable output voltages.With the advantages of high power conversion efficiency,low voltage drop,low temperature rise,low noise and good ripple suppressing capability, it is becoming an increasingly important and necessary electronic device.
