Functional Description
TLE 4266 is a low-drop voltage regulator for 5 V or 10 V supply in a PG-SOT223-4 SMD
package. The IC regulates an input voltage V_I in the range of 5.5 V/10.5 V < V_I < 45 V to
V_Q,nom = 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 a temperature protection which turns
off the IC at overtemperature.
Choosing 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 line 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 whole
operating temperature range.
