Infineon TLS202B1MB V50 linear post regulator

The TLS202B1 is a monolithic integrated fixed linear voltage post regulator for load currents up to 150 mA.

The IC regulates an input voltage VIn up to 18 V to a fixed output voltage of 5.0 V with a precision of ±3 percent. The component can be enabled via the enable input.

It is requiring a permanent connection to a pre-regulator e.g. a DC-DC converter. The regulator is not designed to operate with a direct connection to automotive 12 V battery. A pre-regulator has to be placed in front.

The device is available in a very small surface mounted SCT595 package. (Footprint 2.3 mm x 2.9 mm).
