Introduction

RT9165GX is a high-performance linear voltage regulator specifically designed for use in mobile and multi-media applications. The device is capable of providing up to 150mA current with a 0.9V dropout voltage over a wide range of input voltages from 2.7V to 3.6V. RT9165GX also features low power dissipation and excellent output current stability over temperature. The device is well suited for various mobile applications such as notebook computers, digital cameras and PDAs.

Application Fields

RT9165GX is suitable for applications such as mobile, tablets, digital cameras and other portable applications. The device is also suitable for applications that require low-else current regulation and long battery life. RT9165GX is also suitable for applications such as MP3 players, notebook computers and digital SLRs, where a high efficiency linear voltage regulator provides stable current sourcing and low output noise. RT9165GX provides the flexibility of using various packages, such as VDO, TSOT-23, and SOT-23-3. Each package has the ability to deliver up to 150mA of current.

Working Principle

The RT9165GX is based upon a linear voltage regulator architecture. In this type of voltage regulator, the output voltage is regulated by linear feedback control. The RT9165GX has two voltage control pins, a feedback pin and a feedback reference pin. The feedback pin is connected to the output voltage. The feedback reference pin is connected to a stable voltage reference, usually a bandgap reference. If the feedback pin voltage is below the reference voltage, the regulator increases its output current and the output voltage rises. Conversely, if the feedback pin voltage is higher than the reference voltage, the regulator decreases its output current and the output voltage drops. Thus the feedback control loop regulates the output voltage to a steady level.

The RT9165GX utilizes bi-directional architecture with respect to current flow. The current in each direction is regulated independently by dedicated linear control loops. This allows for better output current regulation over a wide range of input voltages. The bi-directional architecture also enables the device to operate efficiently at light load conditions without sacrificing the output voltage. The RT9165GX can provide up to 150mA current with a 0.9V dropout voltage over a wide range of input voltages from 2.7V to 3.6V, and offers excellent output current stability over temperature.
