NCP693

1A CMOS Low-Dropout

Voltage Regulator

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.
