TECHNICAL DATA
5V/10 V Low-Drop Voltage Regulator
ILE4266-2
Functional Description
ILE 4266-2 is a low-drop voltage regulator for 5 V or 10 V
supply in a P-SOT223-4-2 SMD package. The IC regulates an
input voltage Vi in the range of 5.5 V/10.5 V < Vi < 45 V to
VQrated = 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 uA. The IC
is shortcircuit-proof and incorporates temperature protection
that disables the IC an overheating.

Dimensioning Information on External Components
The input capacitor CI is necessary for compensating line influences. Using a resistor of
approx. 1 Ohm in series with CI, the oscillating of input inductivity and input capacitance
can be clamped. The output capacitor CQ is necessary for the stability of the regulating
circuit. Stability is guaranteed at values CQ ≥10 uF and an ESR ≤10 Ohm within the
operating temperature range.
