ON Semiconductor NCP694 1A CMOS Low-Dropout Voltage Regulators

Excellent Load Regulation, Low Quiescent Current

ON Semiconductor NCP694 1A CMOS fixed output, super low dropout linear voltage regulators are designed for portable battery powered applications with high output requirements up to 1A and -3mV typical load regulation at 1A. ON Semiconductor NCP694 voltage regulators contain a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, and current limit circuits for overcurrent and thermal shutdown. The chip enable function allows for a standby mode with ultra low supply current.

These ON Semiconductor linear regulators feature a maximum operating voltage of 6.0V and a minimum output voltage down to 0.8V (fixed version) and 1.0V (adjustable version). The NCP694 series is ideal for a variety of applications, including battery-powered instruments, hand-held instruments, camcorders / cameras, and portable communications equipment.

Package Type	Pin Number	Pin Name	Pin Description
SOT-89-5	1	ADJ/NC	Adjust pin for NCP694DADJHT1G and NCP694HADJHT1G / No connection
SOT-89-5	2	GND	Power supply ground
SOT-89-5	3	CE	This input is used to place the device into low−power standby. When this input is pulled low, the device is disabled. If this function is not used, Enable should be connected to Vin.
SOT-89-5	4	Vin	Positive power supply input voltage
SOT-89-5	5	Vout	Regulated output voltage
HSON-6	1	Vout	Regulated output voltage
HSON-6	2	Vout	Regulated output voltage
HSON-6	3	ADJ/NC	Adjust pin for NCP694DSANADJT1G and NCP694HSANADJT1G / No connection
HSON-6	4	GND	Power supply ground
HSON-6	5	CE	This input is used to place the device into low power standby. When this input is pulled low, the device is disabled. If this function is not used, Enable should be connected to Vin.
