SHEN ZHEN FINE MAD ELECTRONICS GROUP CO., LTD.
150mA, Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator
The SC9193 is designed for portable RF and wireless applications with demanding performance and space requirements.
The SC9193 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current.
A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in
dropout, further prolonging the battery life. The SC9193 also works with low-ESR ceramic capacitors, reducing the
amount of board space necessary for power applications, critical in hand-held wireless devices. The SC9193 consumes
less than 0.01μA in shutdown mode and has fast turn-on time less than 50μs. The other features include ultra low dropout
voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SC-70,
SOT-23 and WDFN-6L 2x2 packages.
