L4938EPD13TR Datasheet PDF - ST Microelectronics

●The L4938ED and L4938EPD are monolithic integrated dual voltage regulators with two very low dropout outputs and additional functions such as power-on reset and input voltage sense. They are designed for supplying microcomputer controlled systems especially in automotive applications.

●Key Features

● Output 2 voltage 5 V ± 2% with 400 mA current capability (ADJ wired to VOUT2 )

● High precision standby output voltage 5 V ± 1% with 100 mA current capability

● Output 2 disable function for standby mode

● Enable and sense inputs (EN, SI) protected against negative transients down to -5 V

● Extremely low quiescent current, 65 μA (less than 90 μA) in standby mode

● Reset threshold adjustable from 3.8 V to 4.7 V

● Operating transient supply voltage up to 40 V

● Output 2 voltage adjustable by external voltage divider

● Operating DC supply voltage range 5 V - 28 V
