8.2.3.7 LDO1 and LDO2
The LDOs in the TPS650250 are general purpose LDOs which are stable using ceramics capacitors. The minimum output capacitor required is 2.2 μF. The LDOs output voltage can be changed to different voltages between 1 V and 3.3 V using an external resistor divider. Therefore they can also be used as general purpose LDOs in the application. The supply voltage for the LDOs needs to be connected to the VINLDO pin, giving the flexibility to connect the lowest voltage available in the system and therefore providing the highest efficiency.
The total resistance (R5+R6) of the voltage divider should be kept in the 1 MΩ range in order to maintain high efficiency at light load. VFBLDOx= 1.0 V.
