1A CMOS Low-Dropout
Voltage Regulator
The NCP694 series of fixed output super low dropout linear
regulators are designed for portable battery powered applications with
high output current requirement up to 1 A and −3 mV typical load
regulation at 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 overcurrent 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 SOT−89−5 and HSON−6 packages.
Standard voltage versions are 0.8 V, 1.0 V, 1.2 V, 2.5 V, 3.3 V for fixed
version and adjustable output voltage down to 1.0 V.
Features
• Maximum Operating Voltage of 6.0 V
• Minimum Output Voltage Down to 0.8 V for Fix Version and 1.0 V
for Adjustable Version
• Load Regulation −3 mV at 1 A Output Current
• Low Dropout
• Build−in Auto Discharge Function for D Version
• Standby Mode With Low Consumption
• These are Pb−Free Devices
Typical Applications
• Battery Powered Instruments
• Hand−Held Instruments
• Camcorders and Cameras
• Portable communication equipments
