XC6206P502 Datasheet – 5V, Positive Voltage Regulator – Torex

Part Number: XC6206P502

Function: Positive Voltage Regulator

Package: SOT-23, SOT-89, TO-92 and USP-6B Pin Type

Manufacturer: Torex Semiconductor





The XC6206P502 is highly precise, low power consumption, 3 terminal, positive voltage regulators manufactured using CMOS and laser trimming technologies. The series provides large currents with a significantly small dropout voltage.

The XC6206 consists of a current limiter circuit, a driver transistor, a precision reference voltage and an error correction circuit. The series is compatible with low ESR ceramic capacitors. The current limiter’s foldback circuit operates as a short circuit protection as well as the output current limiter for the output pin. Output voltages are internally by laser trimming technologies. It is selectable in 0.1V increments within a range of 1.2V to 5.0V.

The regulator has a low quiescent current and high ripple rejection ratio, making it suitable for use in low-power and noise-sensitive applications. The IC has a compact SOT-23-5 package, which makes it easy to use in space-constrained designs.

LM317T Circuit

Advantages Vs Disadvantages


1. Versatile: can be used in a wide range of applications
2. Precise voltage regulation: allows for accurate and stable output voltage
3. Adjustable output voltage: can be set to meet specific requirements
4. Wide input voltage range: can handle a variety of input voltages
5. Overload and thermal protection: ensures the circuit remains safe even under adverse conditions


1. Heat dissipation: Generate significant heat when regulating voltage, requiring additional heat sinks or cooling systems in some applications

2. Limited output current: It is not designed to handle high output currents and may require additional components to handle larger loads

3. Higher cost: It is more expensive than other voltage regulators, especially fixed regulators



1. How do I calculate the output voltage of an LM317T circuit?

The output voltage of an LM317T circuit can be calculated using the formula: Vout = Vref (1 + R2/R1), where Vref is the reference voltage (usually 1.25V), R1 is the resistor between the ADJ and OUT pins, and R2 is the resistor between the OUT and GND pins.

2. Can this IC be used as a current regulator?

Yes, It can be used as a current regulator by using a sense resistor in series with the load to limit the output current to a desired level. The output voltage will then adjust automatically to maintain the current level.
