STMicroelectronics has announced STPMIC1 PMIC, which is a fully integrated Power-Management IC. It is designed as a companion chip for the STM32MP1 microprocessor and a general-purpose system power management solution.
Low dropout regulator (LDO) is a simple and cost-effective voltage regulator to get a regulated output voltage from a higher input voltage. The special feature of an LDO is its ability to have a very low voltage drop across it when providing a regulated output voltage.
The MIC5219 is an efficient linear voltage regulator with high peak output current capability of 500mA, very low dropout voltage (500mV at full load), and better than 1% output voltage accuracy. Approx.
The MIC5205 is a low current, very low dropout voltage regulator with a maximum current of 150mA and a voltage drop of 165mV at full load. MIC5205 has an Enable pin to provide Zero-current shutdown mode.
The AMS1117 is a popular SMD package 3-pin voltage regulator that is available in many models for fixed and adjustable voltage requirements. The IC can deliver a maximum current of 1A and the output voltage can vary from 1.5V to 5V.
