LD2979M30TR

LD2979 Very low drop voltage regulators with inhibit Datasheet - production data Description The LD2979 is a very low drop regulator available in SOT23-5L. The very low drop-voltage and the very low quiescent current make them particularly suitable for low noise, low power applications and in battery powered systems. SOT23-5L Shutdown logic control function is available on five pin version (TTL compatible). This means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. Features Very low dropout voltage (0.2 V typ. at 50 mA load) Very low quiescent current (typ. 500 A at 50 mA load) Output current up to 50 mA Logic-controlled electronic shutdown Output voltages of 3.0 and 3.3 V Internal current and thermal limit Supply voltage rejection: 63 dB (typ) Only 1 F for stability Temperature range: -25 C to 125 C Package available: SOT23-5L Table 1.
