The TEA5110 is a dual positive voltage regulator specially designed to supply a microprocessor and associated circuits.
The first regulator supplies the microprocessor in normal operating conditions. In standby mode, the regulator has a very high output impedance (current drain less than 1uA) and the microprocessor may be powered by a battery.
The second regulator supplies the peripherals and provides a halt signal to the microprocessor to turn it in standby mode.
