SI9181 General Description
The Si9181 is a 350-mA CMOS LDO (low dropout) voltage regulator. The device features ultra low ground current and dropout voltage to prolong battery life in portable electronics.
The Si9181 offers line/load transient response and ripple rejection superior to that of bipolar or BiCMOS LDO regulators.
The device is designed to maintain regulation while delivering 600-mA peak current. This is useful for systems that have high surge current upon turn-on. The Si9181 is designed to drive the lower cost ceramic, as well as tantalum, output capacitors.
The device is guaranteed stable from maximum load current down to 0-mA load. In addition, an external noise bypass capacitor connected to the device's CNOISE pin will lower the LDO's output noise for low noise applications.
The Si9181 also includes an out-of-regulation error flag. When the output voltage is 5% below its nominal output voltage, the error flag output goes low. If a capacitor is connected to the device's delay pin, the error flag output pin will generate a delayed power-on-reset signal.
The Si9181 is available in both standard and lead (Pb)-free packages.
