RT9166-18GVL Description

Short technical summary and product information.

The Richtek RT9166-18GVL is a low dropout (LDO) linear voltage regulator designed for efficient power management. It provides a stable, fixed output voltage of 1.8V and can deliver up to 300mA of current. The device features a maximum input voltage of 5.5V and a low dropout voltage of 230mV at 300mA.

 

This regulator is suitable for applications requiring a reliable and compact voltage regulation solution. Its SOT-23-3L package makes it ideal for space-constrained designs. The RT9166-18GVL operates within a temperature range of -40°C to 85°C and includes over-current and over-temperature protection features.

 

Key electrical characteristics include a PSRR of 55dB at 1kHz, ensuring good ripple rejection. The positive output configuration and fixed output type simplify circuit design. This component is well-suited for various battery-powered devices and portable electronics where power efficiency and stable voltage are critical.
