Additional Infomation About Product

L4979D, L4979MD Automotive low dropout voltage regulator Datasheet - production data very low output current mode and enabled regulator. The devices drop to 6 A with not enabled regulators. On chip trimming results in high output voltage accuracy (+/-2%). Accuracy is kept over wide temperature range, line and load variation. * 3*&)7 * 3*&)7 The maximum input voltage is 40 V. The max SO-20 SO-8 output current is internally limited. Internal temperature protection disables the voltage regulator output. Features AEC-Q100 qualified Operating DC supply voltage range 5.6 V to 31 V Low quiescent current (6 A typ. 25 C with enable low) High precision output voltage (+/-2%) Low dropout voltage less than 0.5 V Reset circuit sensing the output voltage down to 1 V Table 1. Device summary Programmable reset pulse delay with external Order codes capacitor Package Watchdog Tube Tape and reel Programmable watchdog timer with external SO-8 L4979D L4979D013TR capacitor SO-20 L4979MD L4979MD013TR Thermal shutdown and short circuit protection Automotive temperature range (T = -40 C to j 150 C) Enable input for enabling/disabling the voltage regulator output Description L4979D and L4979MD are low dropout linear regulators with microprocessor control functions such as low voltage reset, watchdog, on/off control.
