The TLE4274GV852ATMA1 is a low-drop voltage regulator optimized for use as a power supply for large-scale integrated circuits (LSIs). It can either be used as a standalone power supply (e.g. in a mobile phone) or as part of a power management system, such as a switching power supply, battery management system or multi-rail power supply.

It features programmable output voltage from 0.8V to 5.2V. The output voltage is set by a voltage divider and feedback resistor, or through an external digital signal with a resolution of 0.1V. The regulator also features under-voltage protection, overload protection and thermal overload protection.

The TLE4274GV852ATMA1 operates in both constant voltage and constant current mode. The output voltage is clamped to a predetermined voltage to enhance the immunity to transient input voltage surges. The operating current is limited by the sense resistor. When the output current is close to the programmed limit, the voltage sense circuit reduces the output voltage and controls the output current. However, the output current is still limited by the external resistor in order to protect the IC from over-current condition.

Due to its low drop out voltage and ultra-low quiescent current (<1 μA), the TLE4274GV852ATMA1 can be used to provide a supply voltage for a range of power-efficient CPUs and microcontrollers. It is also ideal for use in automotive, telecommunications, industrial and medical applications.

The TLE4274GV852ATMA1 is a highly integrated device that comprises a programmable voltage regulator, voltage sense circuit, overload and thermal protection circuit, EMI filter and output voltage regulator into a single package. It has a wide input voltage range of 3V-41V and can be used with various topologies including buck, boost, buck-boost, and flyback. Its high-efficiency (>80%) and small size (14.81 mm X 8.15 mm) allow for flexibility in system design.

The TLE4274GV852ATMA1 is a highly efficient, single-IC solution for providing regulated power and is suitable for use in a wide range of applications. Its programmable output voltage, wide input voltage range, high efficiency, low quiescent current, and ultra-low dropout voltage make it an ideal choice for powering high-performance, low-power applications.
