PMIC - Voltage Regulators - Linear
The S-1335B28-A4T2U3 is a type of linear voltage regulator. It is a low-noise, low-dropout or LDO regulator designed to regulate the voltage of different application-field devices. It has low output noise and very low quiescent current, and its maximum dropout voltage is typically 55 mV.
Application Field
The most common application-field use of this part is in power management systems such as mobile phones, tablets, and other portable devices. It can be used to regulate the output voltage to any specified level, and its quiescent current allows it to be powered from almost any low-voltage source, making it an ideal choice for those applications. It can also be used in other applications such as automotive and computer systems to regulate the voltage, and it also offers excellent transient response.
Working Principle
The S-1335B28-A4T2U3 works by utilizing U-MOS technology, a power-management integrated circuit (PMIC), which is designed to provide efficient regulation of input and output voltages. The LDO regulator circuit works by comparing the output voltage to the reference voltage and an error amplifier which adjusts the output voltage to match the reference voltage. An external resistor sets the output voltage of the device and an external capacitor is used to provide bypass capacitance, as well as to dampen any noise that might be generated by the device.
The U-MOS PMIC contains two diodes in the reference voltage portion of the circuit, which act as an additional current-limiting feature. The LDO regulator is designed to provide a very low dropout voltage, meaning that the voltage of the output will be very close to the voltage the control circuit is required to provide. Additionally, the U-MOS technology allows the LDO regulator to operate with lower input voltages, making it a good choice for applications that require low power dissipation.
The S-1335B28-A4T2U3 is ideal for applications that require low noise, low-dropout, and low-power dissipation, such as portable electronics and industrial or automotive power supplies. By utilizing the U-MOS PMIC, it is able to provide a very clean and consistent output and is rated for operation up to 70V.
