TPS79018DBVTG4 is a low dropout linear regulator from Texas Instruments with adjustable output voltage from 0.825 to 5.25V and input voltage from 1.2V to 6V, making it ideal for applications that require high precision and low noise. This device has been designed to meet the demanding requirements of small form factor applications. It incorporates a 1.0V dropout voltage, current and thermal protections, and an on/off control pin. The chip has a wide operational temperature range of -40°C to +85°C. Typical applications of this device are battery-operated systems, point-of-load converters, power supplies, and power management applications.

The TPS79018DBVTG4 is a low-dropout linear regulator that operates with a low input voltage. It maintains an output voltage of between 0.825V and 5.25V, which is programmed using a resistor divider circuit connected between the OUT pin and ground. The current output of the device can be set up to 1.2A using an external sense resistor connected between the SNS pin and the OUT pin. The input voltage must be greater than or equal to the output voltage plus the dropout voltage.

The TPS79018DBVTG4 contains an internal low-dropout voltage regulator with better accuracy than an external regulator. This linear regulator provides high accuracy and low dropout performance, with a 0.5% initial accuracy. It has a low output voltage noise and a low quiescent current, which makes it very energy efficient. The device is protected against short-circuit and current overload conditions. It has a thermal shutdown feature to protect against overloads that could damage the device.

In addition to the protection features, the device also features an on/off control pin that allows the user to power down the circuit to minimize power consumption. This is useful for applications with frequent power cycle requirements. The TPS79018DBVTG4 also has an active high reset pin to ensure that the output voltage remains stable when the device is powered on. The reset signal is externally programmable, so the user can choose when it occurs.

The TPS79018DBVTG4 is an ideal voltage regulator for applications requiring precision and low noise operation. It has a wide input voltage range, adjustable output voltage, and thermal and current protection features, so it can be used in a variety of applications, such as battery-operated systems, point-of-load converters, and power supplies.
