ADP667ANZ is a linear voltage regulator specifically designed for low standby power applications. It provides precision over-voltage protection, adjustable current-limit, over-temperature protection, small size and low power consumption. This linear regulator is suitable for a wide range of applications, including automotive, consumer and industrial applications.

ADP667ANZ consists of an adjustable low dropout voltage regulator, current-limit and over-temperature protection circuit. It provides stable output voltage regardless of input voltage and load conditions. Furthermore, it offers excellent load regulation, low ripple and noise, fast transient response and high accuracy.

This regulator is designed to provide a regulated output voltage with user-adjustable current-limit setting. It is capable of sourcing up to two amps of output current while maintaining a voltage drop of less than 1.2V. It also provides multiple protection features, such as over-voltage, current-limit, over-temperature and short-circuit protection.

The output voltage of the ADP667ANZ is adjustable via a single external resistor. This adjustable range is from 0.8V up to 6.5V. The input voltage range is from 2.5V to 15V. The maximum output current is 2A and the operating junction temperature range is from -40°C to +125°C. The device also supports over-temperature and over-current protection.

The working principle of ADP667ANZ is based on a linear combination of PMOS and NMOS transistors. The PMOS transistor controls the output voltage while the NMOS transistor controls the current. When the voltage reaches the set point, the PMOS transistor is switched on and the current passes through the NMOS transistor. This effectively regulates the current at the set point. If the input voltage is higher than the output voltage, the PMOS transistor is switched off, resulting in no current flowing through the output.

The ADP667ANZ linear voltage regulator is an ideal choice for low power, low noise and low cost applications. It has a wide operational temperature range and provides precision protection features, ensuring reliable and safe operation. Furthermore, due to its low-dropout feature, the device is highly efficient, which helps to reduce operating costs.
