REGULATORS
Description
Features
The GM66100/1/2 series are 1A ultra low-dropout
linear voltage regulators that provide low-voltage,
high output current from an extremely small
package.
Fixed and adjustable output voltages
Typical 410mV Dropout Voltage @ 1A
1A minimum guaranteed output current
Accurate 1% Guaranteed Tolerance
Current limiting and thermal shutdown
Reverse-battery Protection
The GM66100/1/2 offers extremely low dropout
(typically 410 m V at 1A) and low ground current
(typically 12mA at 1A).
The GM66100 offers 3 Lead packages with a fixed
output voltage options while GM66101/2 offer SO8
packages for fixed and adjustable output voltages
accordingly.
Reversed leakage protection
Fast Transient Response
The GM66100/1/2 is ideal for PC add-in cards that
need to convert from standard 5V to 3.3V, 3.3V to
2.5V or 2.5V to 1.8V. A guaranteed maximum
dropout voltage of 630mV over all operating
conditions allows the GM66100/1/2 provide 2.5V
from a supply as low as 3.13V and 1.8V from a
supply as low as 2.43V.
The GM66100/1/2 is fully protected with over
current limiting, thermal shutdown, and reversed-
battery protection.

Note 1: Exceeding the absolute maximum ratings may damage the device.
Note 2: The device is not guaranteed to function outside its operating rating.
Note 3: Devices are ESD sensitive. Handling precautions is recommended.
Note 4: PD(MAX) = (TJ(MAX) – TA)/θJA, where θJA is junction to ambient thermal resistance

Note 6: VDO = VIN – VOUT when VOUT decreases to 99% of its nominal output voltage with VIN = VOUT + 1V. For output
voltage below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input
voltage being 2.25V. Minimum input operating voltage is 2.25V.

Application Information
The GM66100/1/2 is a low dropout voltage regulator suitable for applications which ultra low dropout
performance is needed. Unlike older NPN-pass transistor designs, where the minimum dropout voltage is
limited by the base-to-emitter voltage drop and collector-to-emitter saturation voltage, dropout
performance of the PNP output of these devices is limited only by the low VCE saturation voltage.
The GM66100/1/2 regulator is fully protected from damage due to fault conditions. Linear current limiting
is provided. Output current during overload conditions is constant. Thermal shutdown disables the device
when the die temperature exceeds the maximum safe operating temperature. Transient protection allows
device (and load) survival even when the input voltage spikes above and below nominal. The output
structure of these regulators allows voltages in excess of the desired output voltage to be applied without
reverse current flow.

Figure 1. Capacitor Requirements
Output Capacitor
An output capacitor is required for the GM66100/1/2 to maintain stability and improve transient response.
Proper capacitor selection is important to ensure proper operation. The output capacitor selection is
dependent upon the ESR (equivalent series resistance) of the output capacitor to maintain stability.
When the output capacitor is 10μF or greater, the ESR value of the output capacitor should be less than
2Ω for the purpose of transient response improvement as well as stability. Ultra-low-ESR capacitors
(<100mΩ), such as ceramic chip capacitors, may promote instability. A low-ESR solid tantalum
capacitor works extremely well and provides good transient response and stability over temperature.
Aluminum electrolytes can also be used, as long as the ESR of the capacitor is <2Ω.
The value of the output capacitor can be increased without limit. Higher capacitance values help to
improve transient response and ripple rejection and reduce output noise.
Input Capacitor
An input capacitor of 1μF or greater is recommended when the device is more than 4 inches away from
the bulk ac supply capacitance or when the supply is a battery. Small, surface mount, ceramic chip
capacitors can be used for bypassing. Larger values will help to improve ripple rejection by bypassing
the input to the regulator, further improving the integrity of the output voltage.
Error Flag
The GM66101 features an error flag (FLG), which monitors the output voltage and sends out an error
signal when the output voltage drops 5% below its expected value. The error flag is an open-collector
output that pulls low under fault conditions and may sink up to 10mA. Low output voltage signifies a
number of possible problems, including an over current fault (the device is in current limit) or low input
voltage. The flag output is inoperative during over temperature conditions. A pull-up resistor from FLG to
either V!N or VOUT is required for proper operation. For information regarding the minimum and maximum
values of pull-up resistance, refer to the graph in the typical characteristics section of the data sheet.

REGULATORS
Enable Input
The GM66101 and GM66102 feature an active-high enable input (EN) which allows on-off control of the
regulator. The EN input has TTL/CMOS compatible thresholds for simple logic interfacing. EN may be
directly tied to VIN and pulled up to the maximum supply voltage.
Transient Response and 3.3V to 2.5V or 2.5V to 1.8V Conversion
The GM66100 series has excellent transient response to variations input voltage and load current. The
device has been designed to respond quickly to load current variations and input voltage variations.
Large output capacitors are not required to obtain this performance. A standard 10μF output capacitor,
preferably tantalum, is all that is required. Larger values help to improve performance even further.
By virtue of its low-dropout voltage, this device does not saturate into dropout as readily as similar NPN-
based designs. When converting from 3.3V to 2.5V or 2.5V to 1.8V, the NPN based regulators are
already operating in dropout, with typical dropout requirements of 1.2V or greater. To convert down to
2.5V or 1.8V without operating in dropout, NPN based regulators require an input voltage of 3.7V at the
very least.
The GM66100 regulator will provide excellent performance with an input as low as 3.0V or 2.5V
respectively. This gives the PNP based regulators a distinct advantage over older, NPN based linear
regulators.
Minimum Load Current
The GM66100/1/2 regulator is specified between finite loads. If the output current is too small, leakage
currents dominate and the output voltage rises. A 10mA minimum load current is necessary for proper
regulation.

The GM66102 allows programming the output voltage anywhere between 1.24V and the 16V maximum
operating rating of the family. Two resistors are used. The resistor values are calculated by:
R1 = R2 x (VOUT/1.24 - 1)
Where VOUT is the desired output voltage. Figure 2 shows component definition. Applications with widely
varying load currents may scale the resistors to draw the minimum load current required for proper
operation (see above).
