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
= 5 V/10 V. The maximum output current is more than 120 mA. The IC can be
Q,nom
switched off via the inhibit input, which causes the current consumption to drop below
10 A. The IC is shortcircuit-proof and incorporates a temperature protection which turns
off the IC at overtemperature.
Choosing External Components
C
The input capacitor
is necessary for compensating line influences. Using a resistor of
