Description

■ Programmable reset pulse delay with external

L4979D 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

very low output current mode and enabled

regulator. The devices drop to 6 µA with not

enabled regulators.

■ Thermal shutdown and short circuit protection

■ Automotive temperature range (T = -40 °C to

■ Enable input for enabling/disabling the voltage

regulator output

The maximum input voltage is 40 V. The max

output current is internally limited. Internal

temperature protection disables the voltage

regulator output.
