This is Low-Drop Voltage Regulator. The 4274GV50 is a low-drop voltage regulator in a
TO220 package. The IC regulates an input voltage up to 40 V to VQrated = 5.0 V (V50), 8.5 V (V85) and 10 V (V10). The maximum output current is 400 mA. The IC is short-circuit proof and incorporates temperature protection that disables the IC at over temperature.

The control amplifier compares a reference voltage to a voltage that is proportional to the
output voltage and drives the base of the series transistor via a buffer. Saturation control
as a function of the load current prevents any oversaturation of the power element.


1. Output voltage tolerance ≤ ± 4 %
