XC62K Series
Negative Voltage Regulators
ETR0313_007a
■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 correction circuit, and an output driver with current limitation.
SOT-23, SOT-89, USP-6B packages are available.
■APPLICATIONS
●Multi-function power supplies. ●Smart phones / Mobile phones. ●Mobile devices / terminals.
