Package
P-SOT223-4-4 (SMD)
TLE 4264 is a 5-V low-drop fixed-voltage regulator in an SOT-223 package. The IC
regulates an input voltage
V
I
in the range 5.5 V <
V
I
< 45 V to
V
Qrated
= 5.0 V. The
maximum output current is more than 120 mA. This IC is shortcircuit-proof and features
temperature protection that disables the circuit at overtemperature.
Dimensioning Information on External Components
The input capacitor
C
i
is necessary for compensating line influences. Using a resistor of
approx. 1
Ω
in series with
C
i
, the oscillating of input inductivity and input capacitance can
be damped. The output capacitor
C
Q
is necessary for the stability of the regulating circuit.
Stability is guaranteed at values
C
Q
≥
10
µ
F and an ESR
≤
10
Ω
within the operating
temperature range.
