MAX8530ETTG2+T

PMIC - Voltage Regulators - Linear

The MAX8530ETTG2+T is a dual supply, low dropout voltage regulator with single output. This device is intended to regulate the voltage on low voltage systems. The MAX8530ETTG2+T has been designed to provide excellent line and load regulation, and very low quiescent current, making it ideal for supply rail regulation and noise suppression. The device includes Under Voltage Lockout (UVLO) protection, current limit and thermal protection.

The MAX8530ETTG2+T is available in a variety of output voltages and provides adjustable outputs with an externally programmable resistor divider. The feedback loop accurately regulates the output voltage with variations in line and load. The adjustable output feature allows the MAX8530ETTG2+T to be used in a wide range of applications.

The MAX8530ETTG2+T operates over an input voltage range of 2.7V to 30V, with a low 5.0V dropout voltage in the range of 2.7V to 5V. The common ground between the input and output allows the device to power outputs with their own negative supplies or ground. The device also features an integrated low RDSON NMOS switch to reduce voltage spikes during transition. The maximum output current is 850mA.

The MAX8530ETTG2+T is ideal for applications that require a low power and reliable voltage regulator, such as industrial and automotive electronics. It is compatible with a wide range of inputs, including lead-acid batteries, automotive power systems and off-the-shelf power supplies. The device can be used in a number of different applications, including portable electronics, battery powered systems, automotive electronics, telecom power equipment, personal digital assistants (PDAs), embedded systems and motor control circuits.

Working Principle

The MAX8530ETTG2+T is designed to provide a stable regulated output voltage with a minimum number of external components. The device employs an internal error-amplifier and feedback loop to regulate the output voltage. The error-amplifier compares the output voltage with a reference voltage, and the difference (error) is used to make adjustments to the drive of the pass transistor. The loop ensures that the output voltage never exceeds the set-point by more than a few millivolts.

The MAX8530ETTG2+T includes several additional features to ensure a reliable and stable output. A power-saving burst mode feature allows the device to enter a low-power state when the output voltage is less than the minimum regulated voltage. This allows the device to operate more efficiently in applications with light load. The device also includes an under-voltage lockout (UVLO) feature which shuts down the device when the input voltage falls below a certain threshold to protect the device from unexpected power failures.
