AN77L05M-E1 is a 5 V low dropout linear-mode voltage regulator, designed to offer a highly accurate and stable output voltage under fluctuating load conditions. It can operate over a wide input voltage range, from 6.5 V to 24 V, making it well suited for automotive and industrial applications. The AN77L05M-E1 is a low quiescent current device, with a LDO voltage output accuracy of ±2%. This accuracy is maintained over the entire temperature range and over the lifetime of the device. The device also features an integrated current limit protection circuit, current limit is set at 130 mA. In addition, the low voltage dropout feature helps to improve efficiency, while the low shutdown current (200 nA) ensures power efficiency. AN77L05M-E1 is also equipped with a thermal protection circuit to prevent latch-up at higher temperature.

The AN77L05M-E1 is based on an internal linear regulator architecture, using a MOSFET as the controlling element. The MOSFET device is capable of switching quickly between supply voltage and load voltage, so that the output voltage is maintained at a constant level without a significant rise in quiescent current. This high switching frequency reduces the power dissipation of the device and improves the overall efficiency of the linear regulator. The device also features a temperature compensation circuit, which helps to maintain the regulated voltage over a wide temperature range.

The AN77L05M-E1 is suited for a variety of applications where a stable and accurate 5 V output is required, including industrial and automotive power supplies and instrumentation. The low dropout characteristics help to ensure that the output voltage is maintained even when the supply voltage decreases, which is important in many applications. The device is also ideal for battery-powered systems, as it can be powered from a 5 V to 24 V DC power supply. It can also be used in conjunction with a 12 V AC or DC power supply, allowing for wide input voltage ranges.

The AN77L05M-E1 offers great flexibility and features, making it an excellent choice for a wide range of applications. With its low quiescent current, accurate output voltage, high switching frequency and temperature compensation circuits, the AN77L05M-E1 is an efficient and reliable way to provide a stable 5 V output voltage. Furthermore, it is a cost-effective solution, as it is less expensive than other linear regulators.
