Low drop voltage regulator

Datasheet

 production data

Features

■ Operating DC supply voltage range 5.6 V to

31 V

■ Low quiescent current (6 µA 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

■ Programmable reset pulse delay with external

capacitor

■ Watchdog

■ Programmable watchdog timer with external

capacitor

■ Thermal shutdown and short circuit protection

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

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. 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.

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. The max

output current is internally limited. Internal

temperature protection disables the voltage

regulator output.
