DESCRIPTION
L4979D-E and L4979MD are low dropout linear regulators with microprocessor control functions such as low-voltage reset, watchdog, on/off control. Typical quiescent current is 100 µA in Datasheet - production data very low output current mode and enabled regulator. On chip trimming results in high output voltage accuracy (±2%). Accuracy is kept over wide temperature range, line and load variation. The maximum input voltage is 40 V.
