SOT-353(SC-75) 、SOT-89-5、TDFN6-2x2
package

 Green Product (RoHS, Lead-Free,

Halogen-Free Compliant)

Applications

 Portable communication equipment

optimized for fast transient response. It
guarantees delivery of 300mA output current. The
device is available in fixed output voltage from

1.0V~4.8V and as an adjustable device with a

1.0V reference voltage.

Based on its low quiescent current consumption
and its less than 1uA shutdown mode, the
GS7132 is ideal for battery- powered applications.
The line transient response and load transient
response of the GS7132 are excellent, thus the
device is suitable for the power supply for
handheld communication equipment. The
regulator is stable with small ceramic capacitive
loads (1µF typical).

 Notebook Computer
 Battery Powered Systems

Pin Configuration

The dissipation pad for the uDFN4-1X1 and TDFN6-2x2 packages should be solder-plated in reference 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 GND pin.

300mA, Fast Transient Response LDO Regulator GS7132

Application Information

Enable

dimensions’ capacitor.
The GS7132 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

The GS7132 contains a foldback over current
protection function. It allows the output current to
reach the maximum value of 0.5A. Then further
decreases in the load resistance reduce both the
load current and the load voltage. The main
advantage of foldback limiting is less power
dissipation in the pass transistor under shorted- load
conditions.

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

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:

Output Capacitor

The GS7132 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
the setting voltage is 2.5V or more and the

capacitor’s dimensions for V

is too small, the

OUT

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

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 thermal

JA

resistance.

The power dissipation definition in device is:

PD = (VDD − V

OUT

) x I

+ VDD x IQ

OUT

As the above equations indicate, it is desirable to

work ICs whose θ

T

does not increase strongly with PD. To avoid

J(MAX)

values are small such that

JA

thermally overloading the GS7132, 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.
