AP2138R-1.5TRG1 is a linear voltage regulator from the Analog Performance (Analogic Corporation) family of Power Management ICs (PMICs).

Linear voltage regulators work by regulating voltage at the output of the device. Input voltages are higher than the output voltage and the excess voltage is dissipated as heat generated within the device. Linear voltage regulators typically provide low-noise, low-distortion output voltage.

AP2138R-1.5TRG1 is specifically designed to provide excellent performance and robustness in low-voltage applications while still delivering excellent power efficiency. It features a core voltage regulator with an output voltage of 1.5V, an adjustable current limit, and an adjustable voltage accuracy.

The AP2138R-1.5TRG1 is designed for low-input voltage applications such as embedded microcontrollers, FPGAs, and DSPs. It has an operating temperature range of -40°C to +85°C and has been tested for ESD up to 2kV HBM.

The core of the AP2138R-1.5TRG1 is an adjustable low-dropout linear voltage regulator with a maximum output current of 2A. It supports a wide input voltage range of 4.5V – 22V, with an adjustable output voltage of up to 1.8V. The device also features an adjustable current limit, enabling the user to limit the amount of current drawn from the input source, and an adjustable voltage accuracy, enabling the user to set the output voltage tolerance.

The AP2138R-1.5TRG1 also has a programmable power saving mode which enables the device to enter into a low power consumption state when not in use, thus saving power and prolonging battery life. It also has a thermal protection circuit which prevents the device from overheating and allows for the safe and reliable operation of the device.
