Chip-scale LDO has low noise and works down to 1.1V

STMicroelectronics’ LD56020 is a 200mA linear voltage regulator that will operate from 1.1 to 5.5V, and has 8.8µVrms output noise (10Hz – 100kHz) and 90dB supply-voltage rejection (1kHz 20mA). There are six output options: 1.0, 1.1, 1.2, 1.8, 3.0 or 3.3V, with 190mV maximum drop-out at 200mA full load – and custom versions outputting from 0.6 to 4.0V can be ...
