GM66150 Series
1.5A ULTRA LOW DROPOUT VOLTAGE
REGULATORS
Description
Features
The GM66150 series of positive fixed and
adjustable regulators is designed to provide up
to 1.5A output with high current, high accuracy,
and extremely low dropout voltage performance.
These regulators feature 300 to 350mV (full
load) dropout voltages, and very low ground
current. Although designed for high current loads,
these devices are also useful in lower current,
extremely low dropout critical systems, where the
minimal dropout voltage and ground current
values are important characteristics.
Ultra Low Dropout Voltage of 350mV @
1.5A with Low Ground Current
Fixed and Adjustable Voltage Versions
Output Current up to 1.5A
Guaranteed 1% Accurate Tolerance
Extremely Fast Transient Response
Reverse-battery Protection
"Load Dump" Protection
TheGM66150 is fully protected against over
current, reversed input polarity (or reversed
battery connection), reversed lead insertion, over
temperature operation, and transient voltage
spikes (positive or negative).
Zero-Current shutdown mode(5-pin
versions) Error flag signals output
out-of-regulation (5-pin versions)
Five lead fixed voltage versions feature logic
level ON/OFF control and an error flag which
signals whenever the output falls out of
regulation.
For GM66151 and GM66152, the ENABLE pin
may be tied to VIN if it is not required for ON/OFF
control. The GM66150 series is available in
3-pin and 5-pin TO-220 and surface mount
SOT-223 and TO-263 packages.

Note 2: Full Load current (IFL) is defined as 1.5A.
Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with
VOUT to VIN
Note 4: VIN = VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse
testing procedures to minimize temperature rise.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current
plus the ground pin current.
Note 6: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 7: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a 200mA load pulse at VIN = 20V (a 4W pulse) for T = 10ms.

GM66150 Series
1.5A ULTRA LOW DROPOUT VOLTAGE
REGULATORS
Application Information
The GM66150 series is a high performance low-dropout voltage regulator suitable for all moderate to high
current/voltage regulator applications. The 350mV dropout voltage at full load makes it especially valuable
in battery powered systems and as high efficiency noise filters in “post-regulator” applications.
Unlike older NPN-pass transistor designs, dropout performance of the PNP output of these devices is
limited merely by the low VCE saturation voltage. The GM66150 family of regulators is fully protected from
damage due to fault conditions. Current limiting is provided. This limiting is linear; output current under
overload conditions is constant.
Thermal shutdown disables the device when the die temperature exceeds the 125°C maximum safe
operating temperature. Transient protection allows device survival even when the input voltage spikes
between -20V and +60V. When the input voltage exceeds about 35V to 40V, the over voltage sensor
temporarily disables the regulator.

Thermal Design
Linear regulators are simple to use. The most complicated design parameters to consider are thermal
characteristics. Thermal design requires the following application-specific parameters:
• Maximum ambient temperature, TA
• Output Current, IOUT
• Output Voltage, VOUT
• Input Voltage, VIN
First, we calculate the power dissipation of the regulator from these numbers and the device
parameters from this datasheet.
PD = IOUT X (1.01VIN - VOUT), Where the ground current is approximated by 1% of IOUT
.
Then the heat sink thermal resistance is determined with this formula:
TJMAX – TA
θSA
=
– (θJC+θCS), where TJMAX ≤125°C and θCS is between 0 and 20°C/W
PD
Capacitor Requirements
For stability and minimum output noise, a capacitor on the regulator output is necessary. The value of this
capacitor is dependent upon the output current; lower currents allow smaller capacitors. GM66150 series
are stable with the 10µF minimum capacitor values at full load. Where the regulator is powered from a
source with a high AC impedance, a 0.1µF capacitor connected between Input and GND is recommended.
This capacitor should have good characteristics to above 250kHz.

Minimum Load Current
The GM66150 regulators are specified between finite loads. If the output current is too small, leakage
currents dominate and the output voltage rises. The 5mA minimum load current swamps any expected
leakage current across the operating temperature range.
Adjustable Regulator Design
The adjustable regulator versions, GM66152 and GM66153, allow programming the output voltage
anywhere between 1.25V and the 26V maximum operating rating of the family. Two resistors are used.
Resistors can be quite large, up to 1M., because of the very high input impedance and low bias current of
the sense comparator: The resistor values are calculated by:
VOUT
R1 = R2 (
– 1)

Where is VOUT 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.

Error Flag
GM66151 and GM66153 versions feature an Error Flag, which looks at the output voltage and signals an
error condition when this voltage drops 5% below its expected value. The error flag is an open-collector
output that pulls low under fault conditions. It may sink 10mA. Low output voltage signifies a number of
possible problems, including an over-current fault (the device is in current limit) and low input voltage. The
flag output is inoperative during over temperature shutdown conditions.
Enable Input
GM66151 and GM66152 versions feature an enable (EN) input that allows ON/OFF control of the device.
Special design allows œzeroB current drain when the device is disabled#only microamperes of leakage
current flows. The EN input has TTL/CMOS compatible thresholds for simple interfacing with logic, or may
be directly tied to ≤ 30V. Enabling the regulator requires approximately 20µA.
