G916
300mA High PSRR, Low Noise, LDO Regulators
Features
General Description
Low, 90µA No-Load Supply Current
Guaranteed 300mA Output Current
Dropout Voltage is 200mV @ 150mA Load
PSRR=65dB @ 120Hz; 55dB @ 1kHz
Over-Temperature Protection and Short-Circuit
Protection
The G916 series is a low supply current, high PSRR,
low noise, and low dropout linear regulator that comes
in a space saving TSOT-23-5, SOT-23-5 package.
The supply current at no-load is 90µA. In the shutdown
mode, the maximum supply current is less than 1µA.
Operating voltage range is from 2.5V to 6.0V. The
over-current protection limit is set at 550mA typical. An
over- temperature protection circuit is built-in in the
Device to prevent thermal overload. These power
saving features make the G916 series ideal for use in
the battery-powered applications such as notebook
computers, cellular phones, and PDA’s.
Fixed Mode: 1.20V~5.00V (G916-XXX)
Adjustable Mode: from 1.25V to 5.50V (G916)
Max. Supply Current in Shutdown Mode < 1µA
Low Output Noise at 28µVRMS with bypass Ca-
pacitor
Stable with low cost ceramic capacitors
The G916 has two modes of operation. When the SET
pin is connected to ground, its output is a pre-set value:
3.3V. There is no external component needed. When an
output other than the preset value is needed, two ex-
ternal resistors should be used as a voltage divider. The
output voltage is then adjusted by the resistor ratio.
G916-XXX is with fixed-mode output. The output voltage
range is from 1.2V to 5.0V.

feedback voltage force to be the same as the 1.25V
bandgap reference. The output voltage, VOUT, is then
given by the following equation:
Detailed Description
The block diagram of the G916 is shown in Figure 1. It
consists of an error amplifier, 1.25V bandgap reference,
PMOS output transistor, internal feedback voltage divider,
mode comparator, shutdown logic, over current protec-
tion circuit, and over temperature protection circuit.
VOUT = 1.25 (1 + R1/R2).
(1)
Alternatively, the relationship between R1 and R2 is
given by:
The mode comparator compares the SET pin voltage
with an internal 350mV reference. If the SET pin volt-
age is less than 350mV, the internal feedback voltage
divider’s central tap is connected to the non-inverting
input of the error amplifier. The error amplifier com-
pares non-inverting input with the 1.25V bandgap ref-
erence. If the feedback voltage is higher than 1.25V,
the error amplifier’s output becomes higher so that the
PMOS output transistor has a smaller gate-to-source
voltage (VGS). This reduces the current carrying capa-
bility of the PMOS output transistor, as a result the
output voltage decreases until the feedback voltage is
equal to 1.25V. Similarly, when the feedback voltage is
less than 1.25V, the error amplifier causes the output
PMOS to source more current to pull the feedback
voltage up to 1.25V. Thus, through this feedback ac-
tion, the error amplifier, output PMOS, and the voltage
dividers effectively form a unity-gain amplifier with the
R1 = R2 (VOUT /1.25 - 1).
(2)
For the reasons of reducing power dissipation and
loop stability, R2 is chosen to be 100KΩ. For G916,
R1 is 164K, and the pre-set VOUT is 3.30V.
When external voltage divider is used, as shown in
Figure 2, the SET pin voltage will be larger than
350mV. The non-inverting input of the amplifier will be
connected to the external voltage divider. However,
the operation of the feedback loop is the same, so that
the conditions of Equations 1 and 2 are still true. The
output voltage is still given by Equation 1.
For G916-XXX, adjust the internal reference and in-
ternal voltage divider. It provides a fixed mode output
ranging from 1.2V to 5V.

the heat spreading capabilities of the PC board and its
copper traces. In the case of a SOT-23-5 package, the
thermal resistance is typically 240°C/Watt. (See Rec-
ommended Minimum Footprint). Refer to Figure 3a &

The die attachment area of the G916’s lead frame is
connected to pin 2, which is the GND pin. Therefore,
the GND pin of G916 can carry away the heat of the
G916 die very effectively. To improve the maximum
power providing capability, connect the GND pin to
ground using a large ground plane near the GND pin.

Capacitor Selection and Regulator Stability
Normally, use a 1µF capacitor on the input and a 1µF
capacitor on the output of the G916. Larger input ca-
pacitor values and lower ESR provide better sup-
ply-noise rejection and transient response. A higher-
value input capacitor (10µF) may be necessary if large,
fast transients are anticipated and the device is lo-
cated several inches from the power source.
Over Current Protection
The G916 uses a current sense-resistor to monitor the
output current. A portion of the PMOS output transis-
tor’s current is mirrored to a resistor such that the
voltage across this resistor is proportional to the output
current. Once the output current exceeds limit thresh-
old, G916 would be protected with a limited output
current. Further more, when the output is short to
ground, the output current would be folded-back to a
less limit.
Power-Supply Rejection and Operation from
Sources Other than Batteries
The G916 is designed to deliver low dropout voltages
and low quiescent currents in battery powered sys-
tems. Power-supply rejection is 65dB at low frequen-
cies. As the frequency increases above 20kHz, the
output capacitor is the major contributor to the rejec-
tion of power-supply noise.
Over Temperature Protection
To prevent abnormal temperature from occurring, the
G916 has a built-in temperature monitoring circuit.
When it detects the temperature is above 145°C, the
output transistor is turned off. When the IC is cooled
down to below 120°C, the output is turned on again. In
this way, the G916 will be protected against abnormal
junction temperature during operation.
When operating from sources other than batteries,
improve supply-noise rejection and transient response
by increasing the values of the input and output ca-
pacitors, and using passive filtering techniques.
Shutdown Mode
Load Transient Considerations
When the SHDN pin is connected a logic low voltage,
the G916 enters shutdown mode. All the analog cir-
cuits are turned off completely, which reduces the
current consumption to only the leakage current. The
G916 output pass transistor would get into high im-
pedance level. There is an internal discharge path to
help to shorten discharge delay time.
The G916 load-transient response graphs show two
components of the output response: a DC shift of the
output voltage due to the different load currents, and
the transient response. Typical overshoot for step
changes in the load current from 10mA to 300mA is
8mV. Increasing the output capacitor's value and de-
creasing its ESR attenuates transient spikes.
Operating Region and Power Dissipation
Input-Output (Dropout) Voltage
Since the G916 is a linear regulator, its power dissipa-
tion is always given by P = IOUT (VIN – VOUT). The
maximum power dissipation is given by:
A regulator's minimum input-output voltage differential
(or dropout voltage) determines the lowest usable sup-
ply voltage. In battery-powered systems, this will de-
termine the useful end-of-life battery voltage. Because
the G916 use a P-channel MOSFET pass transistor,
their dropout voltage is a function of RDS(ON) multiplied
by the load current.
PD(MAX) = (TJ–TA) /θJA,=(150°C-25°C)/240°C/W = 520mW
Where (TJ–TA) is the temperature difference the G916
die and the ambient air,θJA, is the thermal resistance
of the chosen package to the ambient air. For surface

Layout Guide
The output capacitor also must be located a distance
of not more than 1cm from output to a clean analog
ground. Because it can filter out the output spike
caused by the surge current due to the inductive effect
of the package pin and the printed circuit board’s rout-
ing wire. Figure 5 is adjustable mode of G916 PCB
layout.
An input capacitance of ≅ 1µF is required between the
G916 input pin and ground (the amount of the capaci-
tance may be increased without limit), This capacitor
must be located a distance of not more than 1cm from
the input and return to a clean analog ground.
Input capacitor can filter out the input voltage spike
caused by the surge current due to the inductive effect
of the package pin and the printed circuit board’s rout-
ing wire. Otherwise, the actual voltage at the IN pin
may exceed the absolute maximum rating.
