• Manufacturer Part Number: Q67006-A9355
• Description: 5-V Low-Drop Voltage Regulator
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

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:
