UA78L08ACLPRE3

The UA78L08ACLPRE3 is a linear PMIC (power management integrated circuit) voltage regulator that is designed to provide a regulated, local voltage supply to an integrated circuit or other electrical system component. It is intended to provide a stable, adjustable output voltage in unstable input voltage environments, protecting the component\'s operation from power-supply-induced noise or voltage fluctuations. The UA78L08ACLPRE3 can be used in a variety of applications, ranging from high-end consumer products to industrial applications.

The UA78L08ACLPRE3 is a three-pin voltage regulator that uses a self-biased, transistor-controlled, linear feedback loop topology. It features an internal, low-noise, switch-mode charge pump, which boosts the maximum output voltage from the standard 8 V to 12 V. It also features an adjustable internal discharge time, which reduces the stand-by current to just 9 mA. This enables the UA78L08ACLPRE3 to be used in applications where efficient power management is essential, such as battery-powered devices.

The UA78L08ACLPRE3 is designed to operate with a temperature range of -40°C to +85°C and can handle an input voltage range of 4.75 V to 6.75 V. Its high input voltage can help reduce the voltage regulator\'s thermal dissipation and thus enhance its efficiency. Its internal 1.2 MHz switching speed also helps to improve its efficiency.

The UA78L08ACLPRE3 operates with a high-side current limit of 200 mA, so it can provide enough current for most applications. It also features current, thermal, and over-voltage protections. Its over-voltage protection monitors the regulated output voltage and shuts down the device if it rises above the protection threshold. This helps to protect the system from short circuit and other power-related issues.

The UA78L08ACLPRE3 has a high output ripple of less than 50 mV, making it suitable for audio, video and other high-fidelity applications. It also features an extremely low leakage current of only 1 mA, making it ideal for use in mobile and battery-powered devices. The UA78L08ACLPRE3 is also a low-dropout regulator as it can maintain a regulated output voltage with an input voltage close to the output voltage.

In summary, the UA78L08ACLPRE3 is a linear PMIC voltage regulator designed to provide a regulated, local voltage supply to an integrated circuit or other electrical system components. It offers a range of features, such as low-noise switch-mode charge pump, adjustable internal discharge time, high-side current limit of 200 mA, current and thermal protection, and an extremely low leakage current. These features make the UA78L08ACLPRE3 a reliable and efficient solution for power-sensitive applications.
