The AP2111H-1.2TRG1 is a low dropout linear regulator featuring fast start-up, a low current overshoot, and low noise. It is part of the AnalogicTech Specialized Voltage Regulator family, which includes the AP2111H, AP2111H-1.2 and AP2111C.

The AP2111H-1.2TRG1 is a 3V–1.2A dual-output linear voltage regulator that supports both output voltage trim and EN/DIS pin control to enable an external circuit (e.g. USB switch) to control the outputs. The device provides a fast start-up time, meaning there is no need for an external capacitor at the EN/DIS pin to reduce the inrush current. It also has a low current overshoot, making it a good choice for power management applications that require a low-noise voltage source.

AP2111H-1.2TRG1 Application Fields

The AP2111H-1.2TRG1 is suitable for a wide variety of applications such as wireless communication, multimedia, optical storage device, battery-powered device, and portable electronics. It can be used in applications like power management, which requires a fast start-up time, low current overshoot, and low-noise voltage source. It is also suitable for use in battery-powered systems, where its low dropout voltage provides excellent power efficiency.

AP2111H-1.2TRG1 Working Principle

In essence, the AP2111H-1.2TRG1 operates as a linear voltage regulator. It uses the voltage difference between its input and output to dissipate some power, generating heat in the process. The device contains an internal power transistor that is switched on and off by an internal voltage signal. When the input voltage is higher than the reference voltage, current flows through the power transistor, which acts as an open circuit, allowing a drop across its collector-emitter junction. This is what regulates the output voltage, by dissipating power and generating heat.

The AP2111H-1.2TRG1 is designed for low dropout applications, meaning that the dropout voltage is low enough to allow the device to operate even when the input voltage is only slightly higher than the reference voltage. The device also has a fast start-up time, a low current overshoot, and low noise. These features make the AP2111H-1.2TRG1 an ideal choice for low power applications that require a low-noise voltage source.
