NCV4269ADW50R2G Application Field and Working Principle
NCV4269ADW50R2G is a linear Low Dropout(LDO) voltage regulator that is classified under PMIC - Voltage Regulators - Linear. It is a type of low power, low noise, and fast response regulator that is commonly employed in certain applications for the stabilization of System voltages. This type of voltage regulator includes a high PSRR, reverse current protection, power-on reset, and high-temperature thermal shutdown. With a SOT-363 package, NCV4269ADW50R2G is suitable for a very wide range of Power Management Interface Circuits (PMIC) where space is limited.
Unique Features
This linear voltage regulator includes several unique features that make it attractive for a range of applications:
- Wide operating temperature range from -40°C to +125°C
- Accurate output voltage regulation with a 0.8% initial accuracy
- Low output noise is suitable for applications requiring high ripple stability
- High PSRR of 70dB to 85dB that cancels out most of the EMI disturbances
- Reverse current protection and power-on reset circuit
- Wide voltage range of up to 50V that enables it to power more complex circuits
- Very low quiescent current, which helps in saving battery power
- High temperature shutdown protection
- Very low dropout characteristics
Applications
This linear voltage regulator can be used for the following applications:
- Stabilizing the supply for amplifiers
- Increasing the accuracy of various circuits like ultrasound and laser circuits
- Stabilizing the supply for RF transceivers
- Powering the base station circuitry for products like cell phones
- Powering the Complex Programmable Logic Devices (CPLDs)
Working Principle
The NCV4269ADW50R2G voltage regulator works by taking a variable input voltage, typically between 0.6V and 50V, and by lowering it down to a higher rated output voltage. This is done by using a series of transistors, diodes, and resistors, which form the basis of any simple voltage regulator circuit. The voltage regulator takes a constant input voltage and converts it into a constant output voltage.
The output voltage of the voltage regulator is taken from the output pin, which is connected to a ground reference point. The output voltage is then regulated by the feedback circuit, which is composed of the resistor divider or the optocoupler. The output voltage is adjusted by varying the resistance of the divider or by varying the current through the optocoupler. This, in turn, is used to control the control circuit, which, in turn, is used to adjust the gate of the transistor to obtain the desired output voltage.
The voltage regulator is usually designed to provide a constant output voltage. This is done by having the feedback loop constantly adjust the output voltage to match the desired level. If the input voltage is greater than the output voltage, the voltage regulator will reduce the output voltage. Conversely, if the input voltage is lower than the output voltage, the voltage regulator will increase the output voltage.
The NCV4269ADW50R2G voltage regulator is also designed to provide overvoltage and overcurrent protection. It helps protect the circuitry from voltage surges, which can damage the device. It also helps protect the device from overcurrent, which can damage the power supply or cause the circuit to shutdown abruptly.
