LDO Regulators Draw Little Power And Reject Noise

Low power consumption in standby mode and excellent noise ripple rejection characteristics are said to be hallmarks of an expanded range of low drop-out voltage regulators. The BA000LBSG regulators are offered in output voltages from 2.8V to 5V, in increments of 100 mV, and with tolerance of 2.5%. The devices are rated for minimum current of 150 mA with typical output of 280 mA. Package power dissipation for the SOT-23 devices is 170 mW maximum, making them suitable for portable applications. A logic-controlled standby pin turns off the output to that part of the circuit and reduces quiescent current to less than 10 µA (typically just 0.1 µA).
