LM9070
www.ti.com SNVS130E – DECEMBER 1999 – REVISED APRIL 2013 LM9070 Low-Dropout System Voltage Regulator with Keep-Alive ON/OFF Control
Check for Samples: LM9070 FEATURES DESCRIPTION The LM9070 is a 5V, 3% accurate, 250 mA lowdropout voltage regulator. The regulator features an
active low delayed reset output flag which can be
used to reset a microprocessor system on turn-ON
and in the event that the regulator output falls out of
regulation for any reason. An external capacitor
programs a delay time interval before the reset output
can return high. 1 2 Automotive Application Reliability
