LF33CV Datasheet PDF - ST Microelectronics

The LF33CV is a fixed output very low dropout (LDO) voltage regulator with inhibit function housed in 3 pin TO-220 package. The low drop voltage and low quiescent current make this device particularly suitable for battery powered systems, low noise and low power applications. The LF33CV saves board space, cost and requires a capacitor of 2.2µF for stability.
