L6935 High performance 3 A ULDO linear regulator

L6935 is an ultra low drop output linear regulator operating up to 5 V input and is able to support output current up to 3 A. Designed with an internal low-RDS(on) N-channel MOSFET, it can be used for on-board DC-DC conversions saving in real estate, list of components and power dissipation.

Bias input and power input are split to allow linear conversion from buses lower than 1.2 V minimizing power losses.

L6935 provides the application with an adjustable voltage from 0.5 V to 3.0 V with a voltage regulation accuracy of 1 %. soft-start is available to program the output voltage rise-time according to the external capacitor connected.

Enable and Power Good functions make L6935 suitable for complex systems and programmable start-up sequencing.

The current limit at 3 A protects the system during a short circuit. The current is sensed in the power DMOS in order to limit the power dissipation.

Thermal shut down limits the internal temperature at 150 °C with a hysteresis of 20 °C.
