Voltage Regulators XC62KN Series Negative Voltage Regulators General Description DETAILS Features Low Dropout Voltage: 120mV @50mA (-5.0V) Maximum Output Current: 100mA (within Maximum power dissipation, Vout= -5.0V) Output Voltage: -2.1V to -6.0V in 0.1V increments -5.0V, -4.0V, -3.0V, -2.5V standard ( all other voltages are semi-custom ) Highly Accurate: Setup voltage accuracy ± 2% ( ± 1% for semi-custom products ) Low power consumption: TYP 3.0µA [ Vout= -5.0V ] Output voltage temperature characteristics: TYP± 100ppm/°C Line regulation: TYP 0.1 %/V Ultra small package: SOT-23 (150mW) mini-mold : SOT-89 (500mW) mini-power mold The XC62K series are highly precise, low power consumption, negative voltage regulators, manufactured using CMOS and laser trimming technologies. The series achieves high output currents with small input-output voltage differentials, and consists of a high precision voltage reference, an error correction circuit, and an output driver with current limitation. SOT-23 (150mW) and SOT-89 (500mW) packages are available.
