LD59150PURY

The LD59150 is a 1.5 A LDO regulator, designed to be used in several environments. Two versions, Industrial and AEC - Q100 are available. NMOS topology allows RDS(on) of the pass - element to be reduced, which results in a very small dropout voltage even with a very low input supply voltage. Output voltage can be adjusted from 0.8 to 3.6 V by an external resistor divider. The programmable soft - start circuit offers the possibility to control the inrush current at start - up providing a monotonic supply voltage to the load. The LD59150 has enable pin to turn on/off (EN) the regulator and Power Good to monitor the regulated output voltage (PG). The combination of both can be used to set a desired power sequence in case of multiple regulated rails. The LD59150 embeds protection functions, such as: current limit and thermal shutdown.
