Si91841 - 150-mA Ultra Low-Noise LDO Regulator With Discharge Option

Si91841 - Vishay Power ICs SI91841 The SI91841 is a 150-mA CMOS LDO (low dropout) voltage Regulator It is the perfect choice for low voltage, low power applications. An ultra low ground current makes this part attractive for battery operated power systems. The SI91841 also offers ultra low dropout voltage to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the Si91841s ultra low output noise. An external noise bypas capacitor connected to the devices BPpin CAN further reduce the noise level. The SI91841 is designed to maintain regulation while delivering 300-mA peak current, making it ideal for systems that have a high surge current upon turn-on. By Vishay Intertechnology
