XC6203 Series ETR0303_004

Large Current Positive Voltage Regulators

■GENERAL DESCRIPTION
The XC6203 series are highly precise, low power consumption, 3 terminal positive voltage regulators manufactured using
CMOS and laser trimming technologies.
The series provides large currents with a significantly small dropout voltage.

■TYPICAL APPLICATION CIRCUIT
1) CIRCUIT①

2) CIRCUIT②

■NOTES ON USE
1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be
exceeded.

2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output
current. Please keep the resistance low for the VBIAS, VIN and VSS wiring in particular.

3. Please wire the CIN and CL as close to the IC as possible.

4. Capacitances of these capacitors (CIN, CL) are decreased by the influences of bias voltage and ambient temperature. Care
shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence.

5. When it is used in a quite small input / output dropout voltage, output may go into unstable operation. Please test it
thoroughly before using it in production.

6. 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.
