LP3997
Micropower 250mA CMOS LDO Regulator with Error
Flag / Power-On-Reset
General Description
The LP3997 regulator is designed to meet the requirements
of portable, battery-powered systems, providing accurate
output voltage, low noise, and low quiescent current. The
LP3997 provides 3.3V output at up to 250mA load current.
When switched in shutdown mode, the power consumption
is virtually zero.
The LP3997 is designed to be stable with space saving
ceramic capacitors as small as 1μF.
The LP3997 also includes an out-of-regulation error flag.
When the output is more than 5% below its nominal voltage,
the error flag sets to low. If a capacitor is connected to
device’s delay pin, a delayed power-on reset signal will be
generated.
