DESCRIPTION
The Si91841/3 is a 150-mA CMOS LDO (low dropout) voltage
regulator. It is the perfect choice for low voltage, low powerapplications. An ultra low ground current makes this part
attractive for battery operated power systems. The Si91841/3also offers ultra low dropout voltage to prolong battery life in
portable electronics. Systems requiring a quiet voltagesource, such as RF applications, will benefit from theSi91841/3’s ultra low output noise. An external noise bypass
capacitor connected to the device’s BP pin can further reducethe noise level. The Si91841/3 is designed to maintain
regulation while delivering 300-mA peak current, making itideal for systems that have a high surge current upon turn-on.
For better transient response and regulation, an active
pull-down circuit is built into the Si91841/3 to clamp the output
voltage when it rises beyond normal regulation. The Si91841automatically discharges the output voltage by connecting the
output to ground through a 100-� n-channel MOSFET whenthe device is put in shutdown mode.
The Si91841/3 features reverse battery protection to limitreverse current flow to approximately 1-�A in the event
reversed battery is applied at the input, thus preventingdamage to the IC.
The Si91841/3 is available in both standard and lead (Pb)-freepackages.
