MCUs with NXP
LDOs
Ultra small, highly effective power supplies
for driving Cortex M0 microcontrollers
NXP’s low dropout regulators (LDOs) are ideal for powering microcontrollers in many
applications. In particular, our advanced linear portfolio is optimized for applications with
challenging space requirements, high battery lifetime demands and a need for superior
operating stability. The selection table below gives an overview of the recommended LDO
products for different Cortex M0 microcontroller types including the M0+ family.
