PMIC - Voltage Regulators - Linear

The TPS7148QDG4 is a linear voltage regulator, part of a family of highly integrated power management integrated circuits (PMICs) for portable applications. It consists of variable output current limits, short circuit protection, overtemperature protection, power good indicator, and internal soft start. This voltage regulator can be used in a variety of portable devices, from smartphones to handsets and wearables.

Application Fields

The TPS7148QDG4 is designed to provide a stable output voltage while limiting the current in various applications. This product can be used in mobile, desktop and industrial products, as well as medical, automotive, and consumer electronics. It can be used in a variety of systems, including:

• Smartphones and handsets
• Digital media players
• Tablets
• Cameras
• GPS devices

Working Principle

The linear voltage regulator is made up of two parts: a power switch and an integrated resistor. The power switch is used to vary the voltage and current through a feedback circuit. The integrated resistor is used to provide a fixed steady voltage and current corresponding to the input signal.

When the switch is on, current flows through the resistor and the output voltage is determined by the ratio between the internal reference voltage, the fixed voltage and the current flowing through the resistor. When the switch is turned off, no current flows and the output voltage will be manually adjustable.

The feedback circuit is used to monitor the system voltage and current and force the power switch to maintain the desired output voltage. It allows the regulator to adjust the output voltage as the load changes, allowing for smoother power output.

The TPS7148QDG4 also features short circuit protection, overtemperature protection and power-good indicator for added safety and reliability. The internal soft start limits inrush current at turn-on, reducing power supply and output stage stress.
