MMPF0200NPAZES is a high-performance voltage regulator integrated with a low dropout (LDO). It is categorized into PMIC - Voltage Regulators - Special Purpose. It is designed to optimize user flexibility with adjustable output voltage.

MMPF0200NPAZES provides accuracy output voltage, low dropout voltage and high power-supply rejection. The regulator is designed to minimize the overall power consumption with high efficiency. It also offers a shutdown mode to maximize power saving.

MMPF0200NPAZES can be applied in small consumer electronics, low-power system, low-voltage data acquisition and signal conditioning, and short-term battery-powered system. Its wide input voltage range from 2.7V to 5.5V and adjustable output voltage up to 1.8V makes it suitable for multiple applications.

The working principle of MMPF0200NPAZES is in two steps. First, the voltage is divided by resistors, R2 and R3. This voltage is input into the error amplifier A1. The amplified error is then compared to a reference voltage in the bandgap reference that provides temperature stability. This voltage is used to control the gate output of the power PMOS FET. The MOV speeds up the rise time of the output voltage.

The output of the power MOSFET is then regulated by an LDO voltage regulator which further regulates the output voltage into the desired value. The LDO is connected to a bypass capacitor C2 which is used to reduce output voltage ripple.

MMPF0200NPAZES feature many safety functions. It has an enable control pin that allows the user to enable or disable the regulator. It also has an overtemperature protection which limits the die temperature by reducing load current when the die temperature is too high.

To summarize, MMPF0200NPAZES integrated with low dropout (LDO) voltage regulator and a power MOSFET offers adjustable output voltage, low voltage drop, high power-supply rejection and high efficiency due to its low quiescent current. It is suitable for multiple applications with its wide input voltage range and adjustable output voltage up to 1.8V. These features make MMPF0200NPAZES the ideal choice for many consumer electronics, low-power system and low-voltage data acquisition and signal conditioning.
