LE00AB/C series are low voltage low current, internal current limiting linear regulators with an output current of 100mA, available in SO-8 and TO-92 packages.
The LE00AB/C series are very low‑dropout (0.2 V typ) linear regulators available in SO‑8 and TO‑92 packages. They feature an inhibit pin that allows the device to be placed in standby, reducing power consumption for battery‑powered applications. The regulators are pin‑to‑pin compatible with the older L78L00 series.
Key specifications include output voltages from 1.25 V to 12 V, a maximum output current of 100 mA, supply‑voltage rejection of about 80 dB, and operation over –40 °C to 125 °C. The devices require only a 2.2 µF external capacitor for stability, simplifying board layout and reducing cost.
| Dropout Voltage (typ) | 0.2 V |
|---|---|
| Quiescent Current (OFF mode) | 50 pA |
| Maximum Output Current | 100 mA |
| Supply Voltage Rejection (typ) | 80 dB |
| Operating Temperature Range | -40 °C to 125 °C |
The typical dropout voltage is 0.2 V.
In OFF mode the regulator draws 50 pA of quiescent current.
Output voltages are offered at 1.25 V, 1.5 V, 2.5 V, 3 V, 3.3 V, 3.5 V, 4 V, 4.5 V, 4.7 V, 5 V, 5.2 V, 5.5 V, 6 V, and 8 V.
Only a 2.2 µF capacitor is needed for stability.
