RT9078-18GQZ Description

Short technical summary and product information.

The RICHTEK RT9078-18GQZ is a linear voltage regulator designed for applications requiring a stable 1.8V output. It can supply up to 300mA of current with a low dropout voltage of 0.42V at maximum load. The device operates with a quiescent current of 4µA, making it suitable for power-sensitive applications.

 

Key electrical characteristics include an operating voltage range up to 5.5V and a PSRR of 75dB at 1kHz. Protection features such as over current and over temperature are integrated for enhanced reliability. The regulator is controlled via an Enable pin.

 

This component is housed in a 4-ZQFN (1x1) package, also referred to as 4-XDFN Exposed Pad, and is designed for surface mounting. The operating temperature range is -40°C to 85°C (TA).

 

Compliance includes RoHS3, MSL 1, and REACH Unaffected, though these statuses are unverified.
