XC62K Series
ETR0313_006
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 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

*The dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and metal
masking so as to enhance mounting
strength and heat release.
If the pad needs to be connected to other
pins, it should be connected to the VSS pin.

■NOTES ON USE
1) For the phenomenon of temporal and transitional voltage decrease or voltage increase, the IC may be damaged or
deteriorated if IC is used beyond the absolute MAX. specifications.
2) Please ensure that values for input capacitance, CIN and out capacitance, CL, are more than 1μF (Tantalum).
3) Torex places an importance on improving our products and their reliability.
We request that users incorporate fail-safe designs and post-aging protection treatment when using Torex products in their
systems.
