NCP693 Datasheet, PDF (1/12 Pages) ON Semiconductor – 1A CMOS Low-Dropout Voltage Regulator

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.
Features
• Maximum Operating Voltage of 6.5 V
• Low Output Voltage Option down to 0.8 V
• High Accuracy Output Voltage of 1.0%
• Built−in Auto Discharge Function for D Version
• These are Pb−Free Devices
Typical Applications
• Battery Powered Instruments
• Hand−Held Instruments
• Camcorders and Cameras
• Portable communication equipments
