LP3997 Micropower 250mA CMOS LDO Regulator with Error Flag / Power-On-Reset PRELIMINARY May 2004 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.
