PMIC - Voltage Regulators - Linear + Switching encompass integrated circuits (ICs) dedicated to provide power management functions such as Voltage Regulation, Charge Pump circuit, Voltage Step Up or Step Down, Current Limiting and Voltage References. These ICs can be useful for power supplies, general control systems,and communication-type systems.

The RAA230405GFT#AA0 is a device designed for Voltage Regulation, and is an example of PMIC - Voltage Regulators - Linear + Switching. This device is a 4-terminal, low dropout, fixed output linear regulator with internal current limit, thermally protected shutdown and soft-start circuitry. It is ideal for applications needing a low-dropout regulator with a low quiescent current and low noise

Key features of the RAA230405GFT#AA0 include its wide input voltage range of 2V-18V, a fixed output voltage of 5V, and an operating temperature range of -55C to +125C. The quiescent current is 1A at full load, and the specified input and output capacitors are 10uF (ceramic) and 1uF (ceramic), respectively. The device also has an on-chip, current limit circuit which provides protection if the output current exceeds 2A.

The RAA230405GFT#AA0 is suitable for driving relays and other electro-mechanical loads, providing power to microprocessors, powering timers and analog circuitry, and providing backup power supply in emergency situations. It is also useful for portable equipment and systems that require a low-quiescent-current source of stable voltage.

The working principle of the RAA230405GFT#AA0 device is to compare the output voltage to a precision internal reference voltage and generate a control signal necessary to maintain the output voltage constant. The control signal is then used to regulate the current through a pass transistor, which adjusts the output voltage. The RAA230405GFT#AA0 is an inherently stable system, free of oscillations and transient spikes.

In addition to providing Voltage Regulation, the RAA230405GFT#AA0 also provides over-current and thermal protection of the pass transistor by means of an internal current limit and thermal shutdown circuit, which will shut down the pass transistor when the temperature exceeds +125C.

The RAA230405GFT#AA0 device is an efficient and compact Voltage Regulation solution for many different types of applications. Its wide input voltage range and low quiescent current make it an ideal choice for a large variety of applications.
