ELECTRICAL CHARACTERISTIC NOTES
Note 1:
Maximum power dissipation can be calculated using the formula:
P
= (T
- T
) /
θ
, where T
is
the junction temperature, T
is the ambient temperature and
θ
is the junction-to-ambient thermal resistance.
θ
JC
is 6oC/W for this package. Exceeding the maximum allowable power dissipation will result in excessive die
temperature and thermal shutdown protection. For 5 Pin SOT-23
θ
is
191
°
C/W
and
59
°
C/W
for the 8 Pin DFN. A
part mounted on a PC board will deliver improved thermal perfformance based on copper surface area.
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
), 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 VIN to be lower than 4V, timing (T
ON
& T
OFF
) increases slightly.
