RT9058-33GVL is an advanced Voltage Regulator (VR) with low dropout (LDO) feature, developed primarily for the market of mobile phones and tablet PCs. This voltage regulator utilizes Linear Regulator (Linear) technology to provide a stable and precise output voltage, superior efficiency and superior transient response. It is a compact, low-cost and power efficient solution with wide input voltage range. The RT9058-33GVL can be used with various kinds of mobile phones and tablet PCs, such as Samsung, HTC and Apple.

The RT9058-33GVL is designed to provide a very low quiescent current in either active or standby modes. This is mainly because the device reduces the dropout voltage (Vd) between input and output and the power loss is reduced because it does not have to spend time for the component to turn off and turn on again in order to maintain a constant voltage.

It has a wide input voltage range from 1.5V to 4.5V and can output a voltage ranging from 1.2V to 4.0V. It can deliver up to 200mA in current, with excellent transient response and low output ripple. The maximum power efficiency of the device is up to 90%.

The RT9058-33GVL has two pin-compatible packages: 8-pin PSOP and 10-pin DFN packages, both of which are available in 0.5mm pitch and 0.6mm pitch sizes, making the device suitable for a variety of mobile phone and tablet PC applications in case of size limitation. Furthermore, it meets the general mobile phone wireless charging specification of WPC 1.2.

In addition to the low quiescent current, other features also contribute to its efficiency and performance. The RT9058-33GVL features wide temperature range operation, up to 105°C, with an improved transient frequency of extended frequency up to 1MHz and a high dropout voltage of only 60mV at full load with 4.5V input when the output is set to 2.5V. The output voltage is adjustable with a Proportional Integrating (PI) loop, which is enabled by VIN voltage ripple fluttering in detectable manner.

The RT9058-33GVL is ideal for use in densely populated applications, such as mobile phones and tablet PCs, where a low-noise output voltage is required. It is also suitable for battery-powered and consumer applications such as set-top boxes, digital cameras and more.

In conclusion, RT9058-33GVL is a highly advanced voltage regulator with a wide range of features which makes it ideal for a variety of mobile phone and tablet PC applications. The device provides low quiescent current, wide temperature range operation, excellent transient response, high dropout voltage and adjustable output voltage. Therefore, RT9058-33GVL is a great option for mobile phone and tablet PC applications which require a reliable and power efficient solution.
