The AP2210K-ADJTRG1 is a low-dropout regulator (LDO) designed to be a replacement for linear regulator applications in modern electronics designs. It provides precise output voltage regulation without the use of a charge pump or current-dividing circuitry. The AP2210K-ADJTRG1 operates from an input voltage range of 1.8V to 6V, and provides an adjustable output voltage ranging from 0.7V to 6V. Ideal for systems that require very low quiescent current, the AP2210K-ADJTRG1 is a great choice for keeping power supply voltage stable.

Application Field

The AP2210K-ADJTRG1 Linear Voltage Regulator is designed primarily for low-current applications. It can be used in a variety of systems that require high accuracy and low noise supply voltages including high reliability systems, low power logic, LCD backlighting applications, sensitive microprocessor logic, and more.

Working Principle

The AP2210k-ADJTRG1 regulator operates by passing current through an internal resistor divider network which lowers the input voltage. The output voltage is regulated by a voltage feedback loop in which current flowing through the resistor divider is compared to a reference voltage. The feedback loop regulates the output voltage of the AP2210K-ADJTRG1 so that it is equal to the reference voltage plus the voltage across the resistor divider.

The AP2210K-ADJTRG1 also employs a thermal overload protection circuit which turns off power to the regulator when the junction temperature of the die exceeds a certain value. This feature prevents the regulator from being damaged from excessive heat.

The AP2210K-ADJTRG1 also includes a shutdown feature which, when enabled, disables the load temporarily to decrease quiescent current. This feature can be used to reduce power consumption during normal operating conditions.

Thanks to its low noise, excellent line and load regulation, and low quiescent current, the AP2210K-ADJTRG1 is an excellent choice for low-current applications. Its adjustable output voltage allows it to be used in a variety of applications, providing reliable and accurate voltage regulation.
