L4995KTR is a type of linear voltage regulator (PMIC - Voltage Regulators - Linear) that provides a regulated output voltage of up to 20 V with a maximum voltage drop of 0.1 V. It is a three-terminal device, with an input voltage range of 1.2 V to 20 V, and an output current of up to 1 A. Its main features are low drop-out voltage, low quiescent current, 1 A output current capability, and fast output transients.

The L4995KTR is used in a wide range of applications, from low-voltage battery-powered systems to high-voltage automotive applications. In battery-powered systems, it is used to maintain a stable voltage for applications such as consumer electronics, handheld devices, and battery-powered tools. In automotive applications, the L4995KTR is used to regulate the output from alternators, ensuring that the correct voltage is supplied to the vehicle's electrical system.

The working principle of the L4995KTR is based on the combination of a linear regulator and a low-dropout (LDO) regulator. A linear regulator is used to provide a constant voltage output by controlling the output current to maintain the desired output voltage. The LDO regulator is used to provide additional current regulation, allowing the L4995KTR to maintain a constant output voltage over a wider input voltage range. It also helps to reduce the input current in no-load conditions, thus increasing the efficiency of the device.

The L4995KTR has two built-in protection features that protect the device from overvoltage, overcurrent, and thermal overload conditions. The device also has a power-on reset circuit that ensures that the output voltage remains at a safe level until the device has been initialized. Furthermore, the device is designed to operate at low quiescent current and high output impedance, ensuring a low system cost.

In summary, the L4995KTR is a PMIC - Voltage Regulators - Linear device that provides a regulated output voltage of up to 20 V with a maximum voltage drop of 0.1V. It is well-suited to a wide range of applications, from low-voltage battery-powered systems to high-voltage automotive applications. Its main features are low drop-out voltage, low quiescent current, 1 A output current capability, and fast output transients. The device also has built-in protection circuits, as well as a power-on reset circuit to ensure the safe operation of the device.
