40V, Ultra-Low Quiescent-Current
Linear Regulators in 6-Pin TDFN/8-Pin SO
Example 2 (TDFN Package):
T A = +85°C
V IN = 14V
V OUT = 5V
Calculate the maximum allowable package dissipation
at the given temperature as follows:
In Examples 2 and 3, the maximum output current is
calculated as 172mA and 476mA, respectively; howev-
er, the allowable output current cannot exceed 50mA.
Alternately, use Figures 6a and 6b to quickly determine
the maximum allowable output current for selected
ambient temperatures and input voltages.

Output-Capacitor Selection
and Regulator Stability
For stable operation over the full temperature range
Then determine the maximum output current:
and with load currents up to 50mA, use a low-ESR
2.2μF (min) ceramic or tantalum output capacitor. Use
I OUT(MAX) =
1.5478W
14V ? 5V
= 172mA ? I OUT ( MAXX ) = 50 mA
larger output-capacitor values such as 22μF to reduce
noise, improve load-transient response, and power-
supply rejection.
Example 3 (TDFN Package):
T A = +50°C
V IN = 9V
V OUT = 5V
Calculate the maximum allowable package dissipation
at the given temperature as follows:
P D = 1.9048W
Find the maximum output current:
Some ceramic dielectrics exhibit large capacitance and
ESR variations with temperature. Ensure the minimum
capacitance under worst-case conditions does not
drop below 1.3μF to ensure output stability. With an
X7R dielectric, 2.2μF should be sufficient at all operat-
ing temperatures.
