TPS79516DCQR Application Field and Working Principle

The TPS79516DCQR is a highly integrated, easy to use linear voltage regulator with a wide array of features and applications. It is ideal for use in space or power-limited applications requiring high accuracy and low quiescent current. The TPS79516DCQR has high-accuracy voltage feedback, accurate current limiting and full over-current protection. It also includes a fast-start-up current regulator, and adjustable start-up timing. Furthermore, the device includes a shutdown fuse and an output capacitor discharge pin.

The TPS79516DCQR is capable of providing a constant output voltage at the outputs of other devices, and is primarily intended for use in various dc-to-dc converter applications. These converter applications can be divided into two categories. First, the TPS79516DCQR can be used to provide a constant output voltage to variable input voltages, such as in back-up power supplies, boosting converter and buck converter applications. Secondly, the device can be used to provide a constant output voltage for the input of other devices, such as dc-to-dc converters, LCD monitors, and computers.

The TPS79516DCQR linear voltage regulator is a 4-pin, open-collector, active low Regulator with an integrated current-limiting amplifier. The Regulator is powered by a single voltage supply, which is then regulated to generate the desired output voltage. The device features a wide input voltage range (1.8 V to 5.5 V) and output voltage range (1.2 V to 5.5 V). The output current limit is adjustable and can be set to any value between 0.2 mA and 3.2 mA. The output voltage accuracy is high, at 0.5% max, with a maximum line and load regulation of 0.05% over the input voltage range (VI = 1.8 V To 5.5 V). The output ripple-rejection is also quite good, with a maximum of 90dB above 1 kHz. The TPS79516DCQR also features an extremely low quiescent current, with a typical value of 10µA.

The TPS79516DCQR linear voltage regulator provides the required output voltage for a particular application. It has a wide range of uses, from providing a constant voltage for powering LCD displays and computers, to back-up power supplies, electronic devices, and LEDs. In a back-up power supply, the TPS79516DCQR can provide a constant voltage to the device\'s battery and allow it to remain in standby mode even during a power outage. In contrast, the device can also be used as part of an electrical device or LED system, providing a constant voltage to the device, even when the input voltage is fluctuating.

In summary, the TPS79516DCQR is a highly integrated linear voltage regulator device with a wide range of features and applications. It is an ideal choice for power-limited or space-limited applications requiring high accuracy and low quiescent current. The device features accurate voltage feedback, high-accuracy current-limiting and full over-current protection. It also includes a fast-start-up current regulator and adjustable start-up timing. Furthermore, the device has a low quiescent current and high accuracy output voltage control. These features make the TPS79516DCQR linear voltage regulator an attractive choice for a wide variety of applications.
