• Manufacturer Part Number: tle4274gsv33
• Description: Adj.v, 2.6v, 3.0v And 3.3v Standard Regulator
• Manufacturer: Infineon Technologies Corporation

Circuit Description
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. The
IC also includes a number of internal circuits for protection against:
