TPS79118DBVREP Application Field and Working Principle

The TPS79118DBVREP is a 3.3V Linear Low-Noise Voltage Regulator Integrated Circuit (IC) that belongs to the family of PMIC voltage regulators. It is a low dropout (LDO) regulator with guaranteed output current of up to 600mA and input voltage range of up to 24V. The device features dropout voltage of 25mV at full load, low output noise of 5uVrms (typical) over 10Hz - 100kHz, fast transient response time of 2.8us, and a shutdown mode. It is ideal for applications that require noise sensitive circuits, such as portable audio players, current sensor systems and digital TVs.

Functional Overview

The TPS79118DBVREP is an ultralow-noise single-channel LDO voltage regulator with a regulated output voltage of 3.3V. It features fast transient response, low output noise, and low dropout voltage. The device has an input voltage range of 2.2V to 24V, and a maximum output current of 600mA. It has an improved input and output voltage noise that is five times lower than the previous generation of voltage regulators.

The TPS79118DBVREP includes an enable pin that can be used to enable or disable the device. It has a logic-high shutdown state, which causes the output voltage to be pulled to 0.4V. A logic-low enable state allows the output voltage to be set to the desired value. The device is protected against reverse voltage and over-temperature conditions. The TPS79118DBVREP also includes an output enable pin that allows for a fast enable/disable of the output voltage.

Features and Benefits

The TPS79118DBVREP is a linear voltage regulator with a high degree of performance and reliability. It has a wide input voltage range of 2.2V to 24V, and provides a regulated output voltage of 3.3V with low noise of 5uVrms (typical) over 10Hz - 100kHz. The device also has a dropout voltage of just 25mV at full load and a fast transient response time of 2.8us. It is also protected against reverse voltage and over-temperature conditions.

The device has a logic-high enable pin which allows the device to be shutdown quickly, saving power in standby mode and preventing damage to the IC. This state maintains a low output voltage of 0.4V. An internal thermal protection feature also prevents overheating of the device. In addition, the device has a fast start-up time of 1ms and a low quiescent current of just 3mA (typical).

The TPS79118DBVREP is ideal for applications that require a high level of performance and reliability, such as portable audio players, current sensor systems and digital TVs. It is also suitable for use in automotive and consumer electronics applications, as well as general industrial equipment.
