The AP7335A-33W5-7 is a low-dropout (LDO) linear voltage regulator designed for highly efficient and reliable power management for cellular phones, PDAs, and other battery-powered devices. The AP7335A-33W5-7 integrates a control circuit, a reference voltage circuit, a PWM circuit and a current limitation circuit, to provide a highly efficient and low-dropout power management solution. It also features improved current working point trimming, a soft-start/reset circuit, OCP, OVP, and short-circuit protection.

AP7335A-33W5-7 can adjust the output voltage of 3.0V, 3.3V and adjust the accuracy of 0.1V precision. It is based on the Linear voltage regulation technology which enables the output voltage to vary with the input voltage. The output voltage of the LDO is independent of the load current, thus providing a cost-effective solution for power regulation and management. The AP7335A-33W5-7 provides a constant and precise output voltage, within a wide input voltage range, with a maximum rated load current of 7A.

The operating principle of the AP7335A-33W5-7 is as follows. The AP7335A-33W5-7 starts by internally constructing a building block called an error amplifier. In the error amplifier, an input signal is then compared to the reference voltage (also called the “tune pin”) of the regulator and the feedback loop extends to the output. The output voltage is then adjusted with a programmable over voltage protection (OVP) and current limit. This greatly reduces the need for on-board circuits, thereby improving overall system performance.

The AP7335A-33W5-7 is optimized for use in cellular phones, PDAs, digital cameras, MP3 players and other portable electronics that require a consistent low dropout voltage (VLDO). It is also typically used in battery management systems, automotive systems and consumer electronics.

This LDO regulator is ideal for applications such as mobile phones, notebook PCs, small server systems, telecommunications equipment, battery powered motion control, control systems and embedded systems. In addition, because it requires very little input and output ripple, it is a great choice for power management design in audio and video applications.

The AP7335A-33W5-7 is a highly efficient, low-dropout linear regulator perfect for a wide range of applications including cellular phones, PDAs, digital cameras, MP3 players and other portable electronic devices. With its precise voltage adjustment, excellent load transient response, wide input voltage range and low dropout voltage, it provides a reliable and cost-effective power-management solution.
