TLE 4266 G is a 5-V low-drop voltage regulator in a P-SOT223-4-2 SMD package. The
IC regulates an input voltage
V
i
in the range of 5.5 V <
V
i
< 45 V to
V
Qrated
= 5 V / 10 V.
The maximum output current is more than 120 mA. The IC can be switched off via the
inhibit input, which causes the current consumption to drop below 10
µA.
The IC is
shortcircuit-proof and incorporates temperature protection that disables the IC an
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 clamped. The output capacitor
C
Q
is necessary for the stability of the regulating
circuit. Stability is guaranteed at values
C
Q
≥
10
µF
and an ESR
≤
10
Ω
within the
operating temperature range.
