In this mode of operation, the output voltage is the same as the input voltage minus the dropout voltage. The transient performance of the device is significantly degraded because the pass device is in the linear region and no longer controls the current through the LDO. Line or load transients in dropout can result in large output voltage deviations. 8.4.3 Disabled The device is disabled under the following conditions: • The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising threshold. • The device junction temperature is greater than the thermal shutdown temperature. Table 1 lists conditions that result in different operating modes. Table 1. Device Functional Mode Comparison OPERATING MODE PARAMETER VIN VEN IOUT TJ Normal mode VIN > VOUT(nom) + VDO and VIN > VIN(min) VEN > VEN(high) IOUT < ILIM TJ < 125°C Dropout mode VIN(min) < VIN < VOUT(nom) + VDO VEN > VEN(high) — TJ < 125°C Disabled mode (any true condition disables the device) — VEN < VEN(low) — TJ > 158°C |
