Linear Regulators in TDFN
Calculate package dissipation at the given temperature
as follows:
P D = 1.905W
Find the maximum output current:

9 V ? 5 V
= 476 mA ( I OUTMAX = 200 mA )

T A ≤+70°C
In example 3, the maximum output current is calculated
as 476mA, however, the maximum output current can-
not exceed 200mA.
Alternately, use Figure 4 to quickly determine allow-
able maximum output current for selected ambient
temperatures.

Output Capacitor Selection and
Regulator Stability
For stable operation over the full temperature range
and with load currents up to 200mA, use a 10μF (min)
output capacitor with an ESR < 0.5 Ω . To reduce noise
and improve load-transient response, stability, and
power-supply rejection, use larger output capacitor val-
ues such as 22μF.

Selector Guide
Some ceramic dielectrics exhibit large capacitance
and ESR variations with temperature. For dielectric
capacitors such as Z5U and Y5V, use 22μF or more to
ensure stability at temperatures below -10°C. With X7R
or X5R dielectrics, 10μF should be sufficient at all oper-

use 22μF or more to maintain stability. To improve
power-supply rejection and transient response, use a
minimum 10μF capacitor between IN and GND.
