Introduction:

PX8897EDQG-R2-ER1235-A is a special purpose voltage regulator from PMIC (power management integrated circuits). This voltage regulator is designed to function as a high output current, adjustable and low-dropout regulator. It is suitable for supplying current to a wide range of low-voltage and high-power ICs (integrated circuits).

Application field:

This voltage regulator is ideal for providing precise current sources and adjustable power supplies, in order to meet the exact requirements of various signal processing and power management applications. Additionally, it is also suitable for providing power supplies to real time clocks, wireless power amplifiers, personal digital assistants, digital video recorders and digital photography applications, as well as low-voltage and low-noise, high power digital-to-analog (D/A) converters.

Working principle:

The PX8897EDQG-R2-ER1235-A voltage regulator works on a two-current mode, which enables high output current at low voltages. It has a low-dropout voltage of 800mV, which helps to maintain the output of the regulator, even when the input voltage is being reduced. It is also designed with asynchronous output overcurrent protection, so that it can reduce the output current in the case of overload or high temperature conditions.The PX8897EDQG-R2-ER1235-A voltage regulator also has a short-circuit protection, with a current limit which is adjustable via external resistors. This helps to ensure that the voltage regulator will not be damaged by an overload or short circuit, while still providing the required output current.Furthermore, the PX8897EDQG-R2-ER1235-A voltage regulator has an inherent thermal-shutdown feature, which helps protect it from exceeding the safe operating temperature limit. This thermal-shutdown feature also helps to reduce the possibility of the regulator outputting false signals due to overheating.

Conclusion:

In conclusion, the PX8897EDQG-R2-ER1235-A voltage regulator is a highly efficient and reliable device for providing precise current sources and adjustable power supplies for various applications. Its two-current mode, low-dropout voltage, overcurrent protection and thermal-shutdown features all make it an ideal choice for a wide range of power management and signal processing applications.
