Data sheet:
Material Declaration:
LDH40 is a high accuracy voltage regulator designed to be directly connected to a car battery in automotive applications, or a generic battery connected in industrial applications. Extended input voltage up to 40 V makes the device capable to support a load dump transient, typical in automotive systems. Ultra-low quiescent current at light load increases the battery operation lifetime in always-on-standby systems.
The device is stabilized with a small ceramic capacitor on the input and output.
An enable logic control function puts the LDH40 in shutdown mode allowing a total current consumption lower than 0.3 µA. Thermal protection is also included.
The device is available in automotive grade in a very small footprint DFN package with wettable flank, allowing the maximum space saving in the PCB (printed circuit board) design and AOI (automated optical inspection).
- AEC-Q100 grade 1 qualified
- Operating temperature range: -40 °C < TJ < +150 °C
- Input voltage from 3.3 V to 40 V
- Dropout voltage (700 mV typ. at 200 mA load)
- Low ground current (2 μA typ. at no load)
- ADJ from 1.2 V to 22 V
- Output voltage tolerance: 0.5% at 25 °C
- 200 mA guaranteed output current
- Power Good
- Logic-controlled electronic shutdown
- Internal current limit
- Thermal shutdown
- Output active discharge function
- Package options:
- DFN 2x2 6L WF for automotive grade
- SOT23 5L and DFN 6L for industrial
