I've found some discrete LDOs on the net but they needed a lot of components. Fortunately I found A 3.2V LDO capable of giving 100mA . I'll supply the Aref and Op-Amps by the 4.5V and leave only the digital section to be supplied by the 3.2V .
But if you do want to drop some volts you can't go with the regulators everytime and everywhere , there should be some discrete replacement. Farshid |
