TPS7148QD is a low-voltage, dual-output linear regulator from Texas Instruments\' Power Management ICs. This device offers two integrated low-dropout linear regulators that provide a total of 250 mA of output current. The two integrated voltage regulators provide adjustable output voltages from 0.8 V to 6.0 V, as well as up to 40mV of ripple rejection. Additionally, low quiescent current of only 400 µA makes the TPS7148QD ideal for powering low-power integrated circuits, such as microcontrollers, field-programmable gate arrays, and logic chips. It is designed to be used in a variety of applications, including battery-powered systems and home entertainment electronics.

The TPS7148QD uses a combination of an output transistor and a small number of external components to regulate an output voltage in response to an input voltage. The device offers a single on/off enable input, which can be connected to a logic signal. It also features an adjustable soft start capability, which limits in-rush current on power-up and helps to ensure a stable output voltage. In addition, the device includes a voltage-monitoring feature that indicates when the output voltage has been over- or under-driven.

The TPS7148QD includes over-current protection and thermal shutdown to prevent damage to the device during overload conditions. It also offers a wide range of protection features, including over-voltage and under-voltage lockout. This makes it ideal for low-power applications, such as MP3 players, digital cameras, and portable gaming devices. The TPS7148QD is available in a standard, 5-lead SOT-23 package.

The TPS7148QD is a low-voltage linear regulator that can be used in a variety of applications, such as battery-powered systems, home entertainment electronics, and low-power integrated circuits, where a regulated voltage is required. This device offers excellent load regulation, low-dropout voltage, low quiescent current, and over-current protection. The TPS7148QD is available in a standard, 5-lead SOT-23 package, making it an ideal choice for a wide range of applications.
