Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the

device. These are for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability.

Note 2. Devices are ESD sensitive. Handling precaution recommended. Note 3. θJA is measured in the natural convection at TA=25°C on a high effective thermal conductivity

test board (40mm x 40mm x 1.6mm double sided board with 2oz, copper ratio: approx. 50%) of JEDEC 51-7 thermal measurement standard.

Note 6. The output current can be at least this value. Due to restrictions on the package power

dissipation, this value may not be satisfied. Attention should be paid to the power dissipation of the package when the output current is large. The specification is guaranteed by design.

Note 7. The dropout voltage is defined as VIN - V

Low Noise 300mA LDO Regulator GS7119

Application Information

Enable

the setting voltage is 2.5V or more and the The GS7119 has a dedicated enable pin(EN). When the EN pin is in the logic low (VEN<0.3V), the regulator will be turned off, reducing the supply current to less than 1uA. When the EN pin is in the logic high (VEN>1.2V), the regulator will be turned on. Left open, the EN pin is pulled down by a internal resistor to shut down the regulator.

Current Limit and Short circuit current protection

The GS7119 use a current mirror to monitor the output current. A small portion of the PMOS output transistor’s current is mirrored onto a resistor such that the voltage across this resistor is proportional to the output current; this voltage is compared against the feedback voltage. Once the output current cannot exceeds the limit. The

capacitor’s dimensions for V

equal to 1.0mm

OUT

by 0.5mm or smaller than that, the capacitance

value might be extremely low. As a result, the

capacitance might be much less than expected

value. In such cases, the operation might be

unstable at low temperature (-25°C or less). In

that case, use a larger capacity, or a large

dimensions’ capacitor. (For example 1.6mm by

0.8mm)

Input Capacitor

Good bypassing is recommended from input to

ground to help improve AC performance. A 1uF

(X7R) input capacitor or greater located as close

as possible to the IC is recommended. Place the

capacitors physically as close as possible to the

device with wide and direct PCB traces.

Power Dissipation and Layout Considerations

current is set to 480mA typically. When the output voltage is less than 0.2V, the short circuit current protection starts and maintains the loading current to 40mA. The output can be shorted to ground without damaging the device.

Output Capacitor

The GS7119 is specifically designed to employ ceramic output capacitors as low as 1uF (X7R). The ceramic capacitors offer significant cost and space savings, along with high frequency noise filtering. Place the capacitors physically as close as possible to the device with wide and direct PCB traces. Ceramic capacitors have different temperature characteristics and bias characteristics which depend on their dimensions and manufacturers. If

Excessive power dissipation may cause thermal

overload, and hence the increase of the IC

junction temperature beyond a safe operating

level. For continuous operation, it is highly

recommended to keep the junction temperature

below the maximum operation junction

temperature 125°C for maximum reliability.

The relationship between θ

and T

JA

J(MAX)

can be calculated as: P Where T

D(MAX)

= ( T

J(MAX)

− TA ) / θJA

J(MAX)

is the maximum operation junction

temperature 125°C, TA is the ambient

temperature and the θ

is the junction to ambient

JA

thermal resistance. The power dissipation definition in device is: PD = (VIN − V

OUT

) x I

+ VDD x IQ

OUT

As the above equations indicate, it is desirable to

Green Solution Technology Co.,LTD. Rev.:1.47 16 Nov-14

Low Noise 300mA LDO Regulator GS7119

work ICs whose θJA values are small such that T

does not increase strongly with PD. To

J(MAX)

avoid thermally overloading the GS7119, refrain from exceeding the absolute maximum junction temperature rating of 150°C under continuous operating condition. Overstressing the regulator with high loading currents and elevated input-to-output differential voltages can increase the IC die temperature significantly.
