VIPER22 General Description

The VIPER22 is an 8-pin DIP integrated circuit manufactured by STMicroelectronics. It serves as a low-cost, high-performance, low-power, low-dropout (LDO) linear voltage regulator. 


Output Voltage Range: The VIPER22 can provide an output voltage ranging from 1.25V to 15V, making it suitable for a wide range of voltage regulation needs.

Maximum Output Current: It can deliver a maximum output current of 1.5A, making it suitable for powering various electronic devices and components.

Low Dropout Voltage: The regulator exhibits a low dropout voltage of only 0.5V. This means it can maintain a stable output voltage even when the input voltage is close to the desired output voltage.

High Power Supply Rejection Ratio (PSRR): With a PSRR of 70dB, the VIPER22 is effective in rejecting fluctuations and noise in the input power supply.

Low Quiescent Current: The quiescent current is as low as 10μA, which helps conserve power and is beneficial in battery-powered applications.

Thermal Shutdown Protection: It features thermal shutdown protection to prevent the IC from overheating, ensuring its safe operation.

Short-Circuit Protection: The VIPER22 includes short-circuit protection to safeguard the regulator and the connected circuitry in the event of a short circuit.


Automotive Electronics: It can be used in various automotive systems and components, providing stable voltage regulation.

Industrial Control Systems: The regulator is applicable in industrial control systems where reliable voltage regulation is crucial.

Battery-Powered Systems: With its low quiescent current, it is well-suited for battery-powered devices, helping extend battery life.

Portable Electronics: Portable devices and gadgets can benefit from the VIPER22's low dropout voltage and efficient voltage regulation.

Power Supplies: It can be used in power supply units to ensure stable and accurate voltage output.

Telecom Systems: The regulator can be integrated into telecom systems to provide consistent power for various components.
