NSOT-23/SOT-89/TO-92 Package
■General Description
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 inputoutput voltage differentials, and consists of a high precision voltage reference, an error correction circuit, and an output driver with current limitation. SOT-23 (150mW), SOT-89 (500mW) and TO-92 (300mW) packages are available.
■Features
Ultra Small Input-Output Voltage Differential : 50mA output possible with a 0.12V differential (VOUT=-5.0V). Maximum Output Current : 100mA (within max. power dissipation, VOUT= -5.0V) Output Voltage Range : -2.1V ~ -6.0V in 0.1V increments. -5.0, -4.0, -3.0V, -2.5V standard. (All other voltages are semi-custom) Highly Accurate : Output voltage ±2% (±1% for semi-custom products) Low Power Consumption : Typ. 3.0µA @ VOUT= -5.0V Output Voltage Temperature Characteristics : Typ. ±100ppm/°C Input Stability : Typ. 0.1%/V Ultra Small Packages : SOT- 23 (150mW) mini-mold, SOT-89 (500mW) mini-power mold TO-92 (300mW)
