Load isolation switch
When the device is in shutdown mode, a DC current path always exists between the power
source and the load; increasing the standby consumption. A high side switch LDS isolates
the load from the source when the STOD2540 is disabled.
Efficiency
The total consumption of some PMOLED display, can be as low as 1 mA. In order to
increase the battery run time of the device, STOD2540 offers a high efficiency over a wide
range of load and input voltage range.
Under voltage lockout (UVLO)
The minimum supply voltage is 3.0 V, under this value the under voltage lockout circuit
operates with typical threshold 2.8 V.
When supply voltage is below 3.0 V, possible noise in the supply line could disturb the UVLO
circuit causing loss of output regulation. This behavior is eliminated choosing C
higher.
