S-812C49AMC-C3DT2G Application Field and Working Principle
The S-812C49AMC-C3DT2G is a high performance, low power, low-dropout linear voltage regulator (LDO) designed for use in a wide range of consumer electronic equipment. The regulator is designed to provide voltage stabilization, current regulation, and noise reduction in multi-rail systems. It provides precisely regulated voltages, ranging from 1.2V to 5.5V, with an output current capability of up to 900 mA.
The S-812C49AMC-C3DT2G can be used for powering integrated circuits (ICs), digital signal processors (DSPs), microcontrollers, and ASICs. It is also suitable for powering low voltage logic equipment, digital logic ballasts, and active filters used in power supplies. Additionally, it can be used in automotive applications.
Features
- High current output capability of up to 900 mA
- Low quiescent current of 35 µA
- Sub-1 µA shutdown current
- Low dropout voltage of 220 mV
- Input voltage of 2.2V to 5.5V
- Output voltage accuracy of 2.5% over line and load variations
- Excellent line and load regulation over temperature
- High power-supply rejection ratio (PSRR) of 80 dB at 1 kHz
Working Principle
The S-812C49AMC-C3DT2G operates using a low-dropout voltage regulator (LDO) design. It consists of an input stage, a control stage, an error-amplification stage, and an output stage. The input stage senses the input voltage and provides the required bias for the rest of the circuit. The control stage determines the output voltage, and the error-amplification stage amplifies any error to produce an output signal that is proportional to the output voltage. The output stage then drives the output voltage to the desired value.
The S-812C49AMC-C3DT2G uses an error-amplification circuit architecture, which enables the device to provide excellent line and load regulation and low noise. Additionally, the device has a high power-supply rejection ratio (PSRR), which helps to minimize the effects of power supply ripple and fluctuations on the output voltage. The regulator also has low quiescent and shutdown current levels, which ensures low power consumption.
