3 Extended Temperature Solutions

Using TI’s devices that are able to operate in ET environments can greatly simplify the power solution for your design. For example, LMR36015S, is designed to simplify implementation for a wide range of end equipment, including space critical applications and wide thermal requirements. The LMR36015S is in a HotRod package which enables low noise, higher efficiency, and smallest package to die ratio. The device requires few external components and has a pinout designed for simple PCB layout. See Figure 3-1 for a simplified schematic of the device.
