STMicroelectronics LDH40
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. 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.| Part No. | LDH40 |
