XC62KN Series
Negative Voltage Regulators
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 input-output voltage differentials, and
consists of a high precision voltage reference, an error cor-
rection circuit, and an output driver with current limitation.
SOT-23 (150mW) and SOT-89 (500mW) packages are avail-
able.
