ILE4270G, ILE4270S
ICS ILE4270G, ILE4270S OF POWER VOLTAGE REGULATOR
5 V/550MA WITH LOW RESIDUAL VOLTAGE
(FUNCTIONAL EQUVIVALENT TLE4270G BY SIEMENS)
ICs perform stabilizing of output voltage 5 V
with 2% accuracy in the range of input voltages from
5.5 to 26 V, providing a load current not less 550 mA
with residual voltage less than 0.7 V.
The spread of the output voltage is provided by
adjustment of the reference voltage by means of
fusion of diode jumpers on the crystal.
Maximum input voltage 42 V (65 V during the
time t 400 ms).
Fig. 1 – View of IC in
P-TO263-5-1 package
Maximum output current when a short circuit, more
than 650 mA.
ICs are realized in 5-pin plastic packages of
P-ТО263-5-1 and P-TO220-5-12.
ICs are suitable for use in power supply in
electronic equipment including automotive
electronics.

1. Parameters specified in the table are guaranteed for the constant junction
temperature Tj. Measurement of parameters should be conducted by means of pulse
technique.
2. Minus sign before current value indicates current direction only (drain current).
The absolute value of the measured current was adopted as value of current.
3. Measurement of electrical parameters is carried out with connection of input
capacitors CI = 1000 μF, С2 = 470 nF and output capacitor CQ = 22 μF.
