LD2979 series
Very low drop voltage regulators with inhibit
Features

Very low dropout voltage (0.2V typ. at 50mA load) Very low quiescent current (typ. 500uA at 50mA load) Output current up to 50mA Logic-controlled electronic shutdown Output voltages of 3.0; 3.3; 3.8; 5.0V Internal current and thermal limit Supply voltage rejection: 63dB (typ) Only 1uF for stability Selection at 25 C Temperature range: -25 C to 125 C Package available: SOT23-5L and TO-92 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. 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.
SOT23-5L TO-92
