RT9011-CGGQW

PMIC - Voltage Regulators - Linear

The RT9011-CGGQW is a low dropout (LDO) adjustable/fixed linear voltage regulator. It is designed to provide extremely precise voltage regulation while keeping quiescent current consumption under 350uA. It offers ultra-low dropout voltage at 1.2V and output current of up to 350mA. The device is ideal for applications that require precise regulating with minimal power dissipation.

Applications of RT9011-CGGQW

The RT9011-CGGQW is ideally suited for applications requiring low dropout and low noise, such as telecom and GSM systems, industrial control and automation systems, embedded systems, handheld devices, and automotive systems. It is also suitable for power sensitive applications such as image processing, audio/video players, remote sensing systems, internet networking, and magnetic recording heads.

Working Principle of RT9011-CGGQW

The RT9011-CGGQW utilizes a reference voltage, a voltage divider, a feedback amplifier, and a pass transistor to maintain a constant output voltage. The reference voltage is set by the external resistor or the internal resistor and is compared to the internal voltage divider to produce a voltage error. This voltage error is then amplified by the error amplifier and used to adjust the gate of the pass transistor, which controls the output voltage.
