TS5201

200mA Low Noise LDO

Voltage Regulator with Enable

5/7

Version: B07

Application Information (Continue)

The junction to ambient thermal resistance for the minimum footprint is 220

must not be exceeded for proper operation. Using the output voltage of 3.3V and an output current of 120mA, the

maximum input voltage can be determined. From the electrical characteristics table, the maximum ground current for

120mA output current is 2.5mA.

Therefore, a 3.3V application at 200mA of output current can accept a maximum input voltage of 6.23V in a SOP-8

package.

Noise Reduction Capacitors

On adjustable devices, a capacitor from ADJ to GND will decrease high frequency noise on the output. See following

figure:

Minimum Load

The TS5201 will remain stable and in regulation with no load unlike many other voltage regulators. This is especially

important in CMOS RAM keep-alive applications.
