Used as a low-dropout voltage regulator (5V output) or for signal processing in engine management and instrument clusters.
: Integrated safeguards against over-current, over-temperature, and reverse-battery conditions. Pin Configuration (PDIP16) highway 09 ic datasheet
Typical values at VIN = 12V, I_OUT = 500mA, T_A = 25°C, unless otherwise noted. Used as a low-dropout voltage regulator (5V output)
Test the current sensing resistors near the IC. If they have drifted in value or burned out, the IC will incorrectly read the load and trigger a shutdown. Symptom 2: No Power / Device Completely Dead I_OUT = 500mA
