The REG101UA-3 Voltage Regulator is a three terminal fixed output voltage regulator, requiring a minimum amount of external components. Its internal circuitry features include an adjustable output range from 1.2V up to the 5V or 15V rated output, short circuit current limiting and thermal shutdown for full protection. This voltage regulator also incorporates low temperature coefficient and excellent line/load regulation for improved system accuracy and stability. Its output voltage accuracy typically does not exceed ±2%.

The REG101UA-3 is ideal for a wide range of applications ranging from process control, computer systems, and communications, to instrumentation and battery operations. In particular, it has a very low dropout voltage, which allows it to operate even at extremely low voltage supply levels. The device is also designed to handle very high ripple currents and operates at frequencies up to 180kHz.

The REG101UA-3 achieves its output voltage regulation through the Working Principle of Linear Regulators. Linear Regulators are closed-loop control systems which compare the output voltage of the voltage regulator with a reference voltage and adjusts the output voltage in order to obtain the desired output voltage. The regulator circuit usually consists of an error amplifier, feedback elements and transistor or MOSFET pass element. The error amplifier adjusts the voltage level of the transistor pass elements. This allows the transistor to regulate the output voltage correctly.

Consider for example, the REG101UA-3 linear voltage regulator. A power supply with an output voltage other than the desired voltage is applied to the input stage. An internal error amplifier compares the output voltage with an internal reference voltage, and generates an error signal. This error signal is then amplified by applying a gain to it and used to adjust the amount of voltage applied to the transistor pass element. This allows the transistor to regulate the output voltage by only allowing the required amount of current to pass through it. The error amplifier will also adjust the gain to increase or decrease the current if needed.

In summary, the REG101UA-3 voltage regulator is a linear voltage regulator ideal for a range of applications. Its features make it superior to other non-linear regulators, with its low temperature coefficient for improved system accuracy and stability, low dropout voltage for operation even at very low voltage supply levels, and its ability to handle very high ripple currents at frequencies up to 180kHz. Its internal circuitry consists of an error amplifier that compares the output voltage with a reference voltage, and adjusts the output voltage through a transistor or MOSFET pass element in order to obtain the desired output voltage.
