XC62K Series

ETR0313_004

Negative Voltage Regulators

■GENERAL DESCRIPTIO N

The XC62K series are highly precise, low power consumpti on, negative voltage regulators, manufactured us ing 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), SOT-89 (500mW), USP-6B (100mW) and TO-92 (300mW) packages are available.
