Regulator LDO1

10 kHz, VIN3 = 3.3 V, VOUT3 = 2.8 V, IOUT3 = 1 mA

100 kHz, VIN3 = 3.3 V, VOUT3 = 2.8 V, IOUT3 = 1 mA

1 MHz, VIN3 = 3.3 V, VOUT3 = 2.8 V, IOUT3 = 1 mA

Regulator LDO2

10 kHz, VIN4 = 1.8 V, VOUT4 = 1.2 V, IOUT4 = 1 mA

100 kHz, VIN4 = 1.8 V, VOUT4 = 1.2 V, IOUT4 = 1 mA

1 MHz, VIN4 = 1.8 V, VOUT4 = 1.2 V, IOUT4 = 1 mA

1 All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC).2

2 This is the input current into VIN3/VIN4, which is not delivered to the output load.

3 Based on an endpoint calculation using 1 mA and 100 mA loads.

4 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 to output voltages

above 1.7 V.

5 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 3.0 V

output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V, or 2.7 V.

INPUT AND OUTPUT CAPACITOR, RECOMMENDED SPECIFICATIONS

1 The minimum input and output capacitance should be greater than 0.70 μF over the full range of operating conditions. 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 LDOs.
