Description

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.
