The AP2202K-2.6TRE1 is a three terminal negative adjustable linear voltage regulator that is part of the PMIC (Power Management Integrated Circuit) family of voltage regulators. A PMIC is a system-on-chip integrated circuit that integrates one or more regulators, NFETs, and P-CHOPFETs, allowing for centralized control and management of power. The main power management and monitoring functions are implemented in a single chip, making it extremely convenient and efficient to use. The AP2202K-2.6TRE1 linear voltage regulator has a negative voltage adjustable output range of 1.2V to -2.6V, making it ideal for operation in digital power systems, microcontrollers, and other logic devices running at low voltages.

The AP2202K-2.6TRE1 is specifically designed to feature a low standby current of 1.3 μA, high current output up to 1.2A, and low dropout (LDO) voltage of 0.5 V. This linear voltage regulator is also equipped with an active low, resetting power-on reset (POR) signal, which helps prevent erroneous start-up or operation by resetting the system if the voltage is below the pre-set minimum level. Additionally, the AP2202K-2.6TRE1 includes thermal shutdown, reverse current protection, and over-current protection, which prevent catastrophic system failure in cases of excessive current draw or temperature fluctuations.

In terms of application fields, the AP2202K-2.6TRE1 can be found mainly in digital systems, microcontrollers, and logic devices that require an adjustable linear voltage regulation. The chip can also be used in portable devices such as laptops, mobile handsets, and tablets, and even in automotive systems. The AP2202K-2.6TRE1 can also be used in industrial automation systems.

The working principle of the AP2202K-2.6TRE1 linear voltage regulator is relatively simple. The input voltage is compared to an internal reference voltage and then output is set according to the predefined settings. The output can be adjusted between the limits of 1.2V to -2.6V using an external voltage divider or a commercial potentiometer. The regulator operates in current-limited pulse-width modulation (PWM) mode, enabling it to provide excellent ripple rejection and transient response. Apart from the voltage regulation, it also includes a variety of protection and fault management features, such as thermal shutdown, reverse current protection, and over-current protection, to ensure safe system operation.

The AP2202K-2.6TRE1 linear voltage regulator is an ideal solution for applications that require adjustable, low dropout output voltage and current. Its low standby current, low dropout voltage, and integrated fault management features make it an excellent choice for digital power systems, microcontrollers, and logic devices, as well as portable and automotive systems that require adjustable linear voltage regulation.
