Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 3: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Changes in output
voltage due to heating effects are covered by the thermal regulation specification.
Note 4: Dropout-voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the
load current plus the ground pin current.
Note 6: Output noise voltage is defined within a certain bandwidth, namely 10Hz < BW < 100kHz. An external bypass cap
(10nF) from reference output (BYP pin) to ground significantly reduces noise at output.
Note 7: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is
applied, excluding load and line regulation effects. Specifications are for a 300mA load pulse at V IN = 6V for t = 1ms.
Note 8: The wake-up time (T WU ) is defined as the time it takes for the output to start rising after enable is brought high.
Note 9: The total turn-on time is called the settling time (T S ), which is defined as the condition when both the output and
the bypass node are within 2% of their fully enabled values when released from shutdown.
Note 10: For output voltage versions requiring V IN to be lower than 4V, timing (T ON & T OFF ) increases slightly.
