DESCRIPTION
The Si9182 is a 250-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 Si9182 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
500-mA peak current. This is useful for systems that have high
surge current upon turn-on. The Si9182 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 C

LDO’s output noise for low noise applications.
The Si9182 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 Si9182 is available in both standard and lead (Pb)-free
MSOP-8 packages and is specified to operate over the
industrial temperature range of −40 _C to 85 _C.
