Product Overview
The L4931CD33-TR is a 3.3V very low drop Voltage Regulator with inhibit and SOIC LDO regulator case. The very low drop voltage (0.4V) and the very low quiescent current make it particularly suitable for many applications. A TTL compatible shutdown logic control function this means that when the device is used as a local regulator, a part of the board can be put in standby mode, decreasing the total power consumption. It requires only a 2.2µF capacitor for stability.
- Logic controlled electronic shutdown
- Internal current and thermal limit
- Very low quiescent current
