SS6714-50CXTB

SS6714 Negative Voltage Regulator FEATURES Low power consumption. Low temperature coefficient. Output short-circuit protection. Wide operating voltage range. Good input stability. Space-saving packages - TO-92 or SOT-89 DESCRIPTION The SS6714 is a series of 3-terminal negative voltage regulators with output voltages internally set below the positive supply voltage. Since the SS6714 consumes less current and requires a smaller input/output voltage difference than existing industry-standard 3-terminal voltage regulators, higher capacity and longer service life can be provide in battery-powered portable equipment. The SS6714 is ideal as a power source for liquid crystal displays.

GND PIN - Power GND. VIN PIN - Power Supply Input. APPLICATION INFORMATION A capacitor of at least 1µF is required between the output of the SS6714 and ground for stability. Without this capacitor the part will oscillate. Even though most types of capacitor may work, the equivalent series resistance (ESR) should be held to 5 Ω or less if an aluminum electrolytic type is used. Many aluminum electrolytic capacitors have electrolytes that freeze at about -30°C, so solid tantalum capacitors are recommended for operation below -25°C. The value of this capacitor may be increased without limit. A capacitor of at least 0.1µF should be placed from the input of the SS6714 to ground if the lead inductance between the input and power source exceeds 500nH (approximately 10 inches of trace).
