RT9193-33GB Linear Voltage Stabilizer (LDO) RICHTEK Original Stock

explain
RT9193 is designed for portable RF and wireless applications with demanding performance and space requirements. The performance of RT9193 has been optimized for battery powered systems to provide ultra-low noise and low quiescent current. A noise bypass pin can be used to further reduce output noise. The grounding current of the regulator only slightly increased, further extending the battery life.

RT9193 also works with low ESR ceramic capacitors, reducing the board space required for power applications, which is crucial in handheld wireless devices. The consumption of RT9193 in shutdown mode is less than 0.01 μ A. And the fast opening time is less than 50 μ S. Other features include ultra-low dropout voltage, high output accuracy, current limiting protection, and high ripple suppression ratio. SC-70-5, SOT-23-5, TSOT-23-5, WDFN-6L 2x2, and MSOP-8 software packages are available.
