The NCP693 series of fixed output low dropout linear regulators are designed for portable battery powered applications with high output current requirement up to 1 A. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, a current limit circuits for over-current and thermal-shutdown. A standby mode with ultra low supply current can be realized with the chip enable function. The device is housed in the DFN 1.8x2, 0.50P surface mount package. Standard voltage versions are 0.8 V, 1.0 V, 1.2 V, 2.5 V and 3.3 V.
