Description
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.
Features
- Enable and sense inputs (EN, SI) protected against negative transients down to -5 V.
- Reset threshold adjustable from 3.8 V to 4.7 V.
- Extremely low quiescent current, 65 µA (less than 90 µA) in standby mode.
- Operating DC supply voltage range 5 V - 28 V.
- Operating transient supply voltage up to 40 V.
- High precision standby output voltage 5 V ± 1% with 100 mA current capability.
- Output 2 voltage 5 V ± 2% with 400 mA current capability (ADJ wired to VOUT2).
- O.
