XC62K Series
Negative Voltage Regulators
ETR0313_001
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 (150mW), SOT-89 (500mW), USP-6B (100mW) and TO-92 (300mW) packages are available.
APPLICATIONS
Battery powered equipment Portable & cellular phones Various portable equipment Power supply for GaAs applications
