Product overview

Description

The LM2931 are very low drop regulators. The very low drop voltage and the low quiescent current make them particular suitable for low noise, low power applications and in battery-powered systems. In the 8-pin configuration (SO-8), fully compatible with the older L78L family, a shutdown logic control function is available. This means that when the device is used as a local regulator it is possible to put a part of the board in standby, decreasing total power consumption. Ideal for automotive applications, LM2931 is protected from reverse battery installations or 2 battery jumps. During the transient, such as a 60 V load dump, when the input voltage can exceed the specified maximum operating input voltage of 26 V, the regulator automatically shuts down to protect both internal circuitry and the load.

  • All features

    • AEC-Q100 qualified (DPAK only)
    • Very low dropout voltage (90 mV typ. at 10 mA load)
    • Low quiescent current (typ. 2.5 mA, at 100 mA load)
    • Output current up to 100 mA
    • Adjustable (from VOUT = 2.5 V only SO-8) and fixed (3.3 V and 5 V) output voltage version
    • Internal current and thermal limit
    • Load dump protection up to 60 V
    • Reverse transient protection up to - 50 V
    • Temperature range: - 40 to 125 °C
    • Package available: TO-92, DPAK, SO-8 (with inhibit control)
