STMicroelectronics LD59150
The LD59150 is a 1.5 A LDO regulator, designed to be used in several environments. 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).| Part No. | LD59150 |

DESCRIPTION
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 combination of both can be used to set a desired power sequence in case of multiple regulated rails.
