RichTek Technology Corporation PMIC - Voltage Regulators - Linear RT9198-29GBR

The RT9198-29GBR is a low noise, ultra-fast CMOS linear voltage regulator designed for portable RF and wireless applications. It provides a maximum output current of 300mA and operates with a low dropout voltage of 220mV at full load. The device features a wide input voltage range from 2.5V to 5.5V and offers output voltage options from 1.5V to 5.0V in 0.1V increments. This regulator is optimized for battery-powered systems, boasting a quiescent current of less than 0.01OºA in shutdown mode, which helps prolong battery life. It supports low-ESR ceramic capacitors, minimizing board space requirements, and has a fast turn-on time of less than 50Oºs. Additional features include current limiting protection, thermal shutdown protection, and a high power supply rejection ratio, making it suitable for various applications such as cellular handsets, battery-powered equipment, and portable information appliances. The RT9198-29GBR is available in multiple package types, including SOT-23-5, TSOT-23-5, and SC-70-5.
