5-V Low-Drop Voltage Regulator

Siemens AG 

TLE 4266

Circuit Description

The control amplifier compares a reference voltage, which is kept highly accurate by

resistance adjustment, 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 incorporates a

number of internal circuits for protection against:

q Overload,

q Overtemperature,

q Reverse polarity.
