LM9070S Datasheet

Low-Dropout System Voltage Regulator with Keep-Alive ON/OFF Control


The LM9070S is a 5V, 3% accurate, 250 mA low- dropout 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. LM9070S Features • Automotive Application Reliability• 3% Output Voltage Tolerance• Insensitive to Radiated RFI• Dropout Voltage Less than 800 mV with 250 mA Output Current• Externally Programmed Reset Delay Interval• Keep-Alive Feature with 2 Logic Control Inputs• 60V Load Dump Transient Protection• Thermal Shutdown• Short Circuit Protection and Disable Safety Features• Reverse Battery Protection• Low OFF Quiescent Current, 50 μA Maximum• Wide Operating Temperature Range −40°C to+125°C• TO-263 and 20-Pin Power Surface Mount Packages• Lead Form Compatible with TLE4267 TO-220 Regulator
