Introduction to TLE4274DV33ATMA2

The TLE4274DV33ATMA2 is a narrow-body, low-dropout, linear voltage regulator with a 3.3V output voltage. It belongs to the Power Management Integrated Circuits family of voltage regulators, Linear type. Its field of application is various in terms of power, ranging from home appliances to automotive ECUs, while its low-voltage protection is suitable to be used in portable systems.

Operating Principles

The working principle of the TLE4274DV33ATMA2 is based on a charge pump voltage reference and a low dropout three-level current switch. This linear regulator is designed to provide accurate output voltage control in a wide range of operating conditions. The operating voltage of the TLE4274DV33ATMA2 is from 3.3V to 6.5V. At startup, the charge pump builds up the reference voltage. Once the reference voltage is established, the TLE4274DV33ATMA2 is armed and ready to keep the output voltage steady. The power supply can be quickly and accurately adjusted using the Enable pin. When the Enable pin is pulled low the output is off, the current drawn by the device is completely switched off. With a high pulse on the Enable pin, the TLE4274DV33ATMA2 is enabled, setting the output voltage as specified.

Features of TLE4274DV33ATMA2

The TLE4274DV33ATMA2 is a low-dropout, linear voltage regulator with a 3.3V output voltage. It is designed to be used in portable as well as automotive and household applications with a wide range of operating conditions.The TLE4274DV33ATMA2 features a low dropout of 120mV and an output current of 1.5A. The output voltage is adjustable between 0.1V and 4.5V. It also has a guaranteed line and load regulation of 0.2%. The tolerance of the output voltage is ± 5% over a temperature range of -40°C to 85°C.The device includes a shut down mode that provides complete turn-off of the output when the Enable pin is pulled low. Power on reset circuit is also included that helps protecting the device against invalid operating conditions.

Applications of TLE4274DV33ATMA2
