L6933H1.2 High Performance 2A ULDO Linear Regulator with Soft Start

The L6933H1.2 ultra low drop output linear regulator operates from 2 V to 14 V and is able to support output current up to 2 A. Designed with an internal 50 mΩ N-channel MOSFET, it can be used for on board DC-DC conversions saving in real estate, list of components, low noise generation and power dissipation. L6933H1.2 is available as adjustable version from 1.2 V to 5 V with a voltage regulation accuracy of 1 %. A Soft Start function allows the device to smoothly increase the Output Voltage at the start-up, avoiding overshoot. Inhibit function is provided.

The upper current limit is fixed at 2.5 A to control the current in short circuit condition within ± 8 %. The current is sensed in the power MOS in order to limit the power dissipation.

The device is also provided with a thermal shut down that limits the internal temperature at 150 °C with a histeresys of 20 °C
