The AP2121N-1.8TRE1 is a linear voltage regulator. The device is a low dropout (LDO) linear voltage regulator which provides a regulated output voltage of 1.8V capable of supplying 1A over a temperature range of -40 to +85 C. This voltage regulator is ideal for devices which have low power consumption, such as portable devices, digital cameras, etc. It is also suitable for use in car navigation systems. The AP2121N-1.8TRE1 uses a combination of bipolar and MOS transistors to provide the regulated output. It operates in the linear mode, which means that the output voltage is maintained over the input voltage range of 2.6 to 5.5V. The regulator operates with a dropout voltage of 160mV, meaning that it can provide a regulated output even when the input is close to the output voltage.The AP2121N-1.8TRE1 also offers improved protection against temperature-induced output overshoot, making it suitable for high power applications. In addition, the IC includes over-temperature protection. The voltage regulator also includes built-in protection against over-current, reverse current, and reverse voltage conditions. The device is available in a small SOT-223-5 package and can be used in applications where board space is limited.This voltage regulator is also capable of providing current-limiting protection. It includes an internal current-limiting circuit which limits the output current to 1.5A when the applied input voltage is above 4.7V. It also includes a foldback current-limiting mode which further reduces the output current when the applied input voltage is below 4.7V. The current-limiting feature can be used to protect the load from over-current conditions.The AP2121N-1.8TRE1 also offers improved output accuracy. It has a guaranteed accuracy of 0.4%, making it suitable for use in precision applications. The device also exhibits excellent line and load regulation, with an output voltage error of less than 1% over the full range of load conditions. It also has a low minimum load current of 10mA, making it suitable for low power energy saving products.In addition, the AP2121N-1.8TRE1 offers excellent thermal stability. The thermal shutdown temperature can be adjusted using the external sense resistor. It also features a low-noise operation with minimal power supply noise and includes built-in EMI filtering which helps minimize interference caused by the input voltage. The voltage regulator also features low output impedance which helps reduce noise and ripple.Overall, the AP2121N-1.8TRE1 is a high performance linear voltage regulator. It is capable of providing a regulated voltage of 1.8V and can handle currents up to 1.5A. It also offers improved output accuracy and line and load regulation, as well as improved protection against current-limiting, reverse current, and reverse voltage conditions. It is widely used for low power applications such as portable devices, digital cameras, car navigation systems, and other precision applications.
