The AP2114H-2.5TRG1 is an adjustable low dropout voltage regulator (LDO). It provides a neat solution for power management in applications that require an adjustable output voltage with lower dropout voltage. It provides a wide range of flexible power supply solutions, with fast transient response and controlled turn-on time. The AP2114H-2.5TRG1 is based on a 120V Bipolar Junction Transistor (BJT) as the output device, and a linear voltage regulator as the regulating circuit. It has a wide input voltage range of 4.5 V to 30 V, and an adjustable output voltage range of 0.5 V to 8 V. The dropout voltage of the device is typically 0.2 V at full load, with a maximum operating temperature of 85°C.

The AP2114H-2.5TRG1 is an ideal solution for applications where a low voltage drop and tight output voltage regulation is necessary, such as hand-held electronic devices, mobile phones and other battery-powered systems. The device is also suitable for use in automotive applications, such as audio system power supplies, car navigation systems and instrument clusters.

The AP2114H-2.5TRG1 has a low quiescent current of 8 mA and can support output currents of up to 1 A. The device operates from an input voltage of 4.5 V to up to 30 V, with a minimum input current of 10 mA. The device is extremely efficient, providing more than 95% power conversion efficiency when the input voltage and output current are within the specifications. It is also capable of rejecting up to 100 dB of noise and ripple.

The AP2114H-2.5TRG1 uses a linear, voltage regulation technique to provide the output voltage regulation. A voltage divider is created by connecting a trimmer and a resistor with a Bipolar Junction Transistor (BJT), to set the output voltage. The trimmer is adjusted to set the output voltage, and the load current is drawn from a BJT transistor, which is connected to the output of the regulator. The BJT transistor is controlled by the base current, which is determined by the voltage divider. This results in a voltage drop across the output, so the output voltage will remain constant, irrespective of the load current.

In addition to the voltage regulation, the device also features over temperature protection, which monitors the junction temperature and shuts down the device if the temperature exceeds a predetermined limit. The device also offers over-voltage and over-current protection, so that if there is an overload on the output, the device will shut down to protect itself from damage.

The AP2114H-2.5TRG1 is a robust and efficient low dropout voltage regulator, capable of providing a regulated output voltage with low dropout and good transient response. It is suitable for use in a variety of applications, including handheld electronic devices, mobile phones and other battery-powered systems, and automotive systems such as audio system power supplies, car navigation systems and instrument clusters. The device offers excellent power conversion efficiency and a wide operating voltage range, making it an ideal choice for cost effective power supply solutions.
