PMIC (Power Management Integrated Circuit) is a type of integrated circuit that is designed to manage and regulate the power supply of various electronic devices. In particular, Voltage Regulators – Linear, such as the AP7365-30EG-13 from Diodes Incorporated, are designed to provide a stable output voltage from a unregulated input voltage.

AP7365-30EG-13 Application Field

The AP7365-30EG-13 is a lowcost linear voltage regulator which is ideal for a wide range of portable electronics applications since a breakdown voltage can be set to higher than the most common batteries’ voltage. Currently, this product is used widely in portable electronic devices such as tablet PCs, GPS navigation systems and other handheld devices.

AP7365-30EG-13 Operating Principle

The operating principle of the AP7365-30EG-13 is based on a PNP transistor combined with a resistor and a diode. The PNP transistor is connected to the unregulated input voltage and the output voltage. The resistor controls the output voltage magnitude. The diode provides reverse current protection from the output voltage to the input voltage. To adjust the output voltage magnitude, the resistor is connected to a trim pin allowing the external setting of the regulation voltage.

Input Voltage Range and Minimum Dropout Voltage

The AP7365-30EG-13 can regulate input voltage ranging from 1.5V to 30V, with a minimum dropout voltage of 0.45V at a 1A load. The maximum output current is 1A. There is over-current, over temperature and reverse current protection built-in ensuring the device’s stability and safety. It also has an ultra-low quiescent current of 0.2mA.

Package and Thermal Characteristics

The AP7365-30EG-13 comes in a TO-252-3 package which is easy to install on a PCB. The thermal characteristics of the device can handle up to 4W at ambient temperature from -40C to +85C. It also provides a good thermal margin in excess of 150C/W.

Summary

The AP7365-30EG-13 is an ideal linear voltage regulator for a wide range of portable electronics applications. Its operating principle is based on a PNP transistor combined with a resistor and a diode and can regulate inputs ranging from 1.5V to 30V with a minimum dropout voltage of 0.45V at a 1A load. The device also provides over-current, over temperature and reverse current protection and comes in a TO-252-3 package with a good thermal margin in excess of 150C/W.
