See Figure 10 for the typical load regulation performance for loads less than 1 mA. 2 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output voltages below −3 V. 3 Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% of the nominal value. 4 Current-limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a −5 V output voltage is defined as the current that causes the output voltage to drop to 90% of −5 V, or −4.5 V. INPUT AND OUTPUT CAPACITANCE, RECOMMENDED SPECIFICATIONS Table 2.

The full range of operating conditions in the application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended; Y5V and Z5U capacitors are not recommended for use with any LDO. |
