Logic Controlled Regulator
U
DESCRIPTIO
The LT®1036 features two positive regulators in the same
package. The 12V main regulator offers excellent
performance while supplying load currents up to 3A, and
the 5V auxiliary regulator provides similar performance
while supplying lighter loads of 75mA. The main regulator
has the additional feature of being under the shutdown
control of a logic signal. When the enable pin is taken to a
low logic level, the main regulator shuts down and its
output voltage goes to near 0V. During this command, the
auxiliary output is unaffected by the main regulator’s
condition and continues to provide a 5V output.
FEATURES
■
Two Regulated Outputs:
12V at 3A
5V at 75mA
■
2% Output Voltage Tolerance
■
60dB Ripple Rejection
0.7% Load Regulation
TTL and CMOS Compatible Logic Control

■
■
■
The main output has current and power limiting combined
with thermal shutdown to make it virtually blowout proof.
The auxiliary output is not affected by the thermal
shut down mechanism or the state of the main output,
allowing it to be used as a back-up in case of overloads or
shorts on the main supply.

The logic input of the LT1036 (enable pin) has a 1.6V
threshold and can be driven from a high source
impedance. This allows it to be driven by most logic
families, including TTL and CMOS.

APPLICATIO S I FOR ATIO
General Information
The low quiescent current drain of the LT1036 makes it
usefulinbattery-poweredorbatteryback-upapplications.
The enable pin can be used as a “low battery” detector or
to shut down major portions of system power, allowing
memory portions to continue to operate from the auxiliary
output. At low output currents, the auxiliary output will
regulate with input voltage typically as low as 6.2V, giving
maximum battery life.
The LT1036 is a dual output regulator. The main 12V
output is capable of delivering up to 3A of load current and
can be shut down with a logic signal. The auxiliary 5V
output supplies a minimum of 75mA and is unaffected by
the logic signal. The outputs are trimmed to ±2% initial
tolerance and exhibit excellent line and load regulation.
The logic control feature makes the LT1036 ideal for many
system applications where it is desirable to power-up a
portion of the system for a period of time, and then power
thesystemdownduringastandbyoperation. Applications
such as multiple power supply sequencing, elimination of
expensive AC and DC power switches, delayed start ap-
plications, switching 12V DC loads, and many others are
now easily accomplished.
Good design practice with all regulators is to bypass the
input and output terminals. A 2µF solid tantalum at the
input and at both outputs is suggested. For the applica-
tions which follow, the bypass capacitors are still recom-
mended, but for simplicity are not shown on the diagram.
It is also recommended that for maximum noise immunity
the voltage enable pin be tied high if it is unused. It can be
tied directly to VIN, as shown in Figure 1, or to the auxiliary
Output. If the enable pin is left open, it will float to a high
logic level of approximately 1.6V and the main output
regulator will be at 12V.
Timing functions, such as delayed power-up or power-
down, can also be performed directly at the enable pin.
Becausealogiclowontheenablepinshutsdownthemain
regulator, feedback from output to enable can be used to
generate hysteresis or latching functions.
The enable pin is fully protected against input voltages up
to 30V, even if the power input voltage is zero.

Main Output Current Voltage Characteristics
LT1036M/1036C • AI01
Following a high to low transition at the enable pin, the
main regulator output will begin to drop after a delay of
approximately 0.4µs. With no capacitive load, the output
will fall to zero in approximately 0.8µs (RL = 4Ω to 100Ω).
Withacapacitiveload,falltimeislimitedbytheRCproduct
of the load and the output capacitance. For light loads
(RL>400Ω), the discharge time is controlled by an
internal current pull-down of 15mA for output voltages
down to 1.5V. Below 1.5V, the pull-down current drops to
≈ 4mA. The DC output voltage in the shutdown mode is
approximately 0.12V due to an internal current path in the
regulator. (See Figure 4.)

Driving the Enable Pin
The user should note that the output in the low state can
only sink about 3mA. If current is forced into the output,
the output voltage will rise to 1V at 5mA and about 1.5V at
10mA. With no output capacitor, the rise time of the main
output is about 12µs. With an output capacitor, rise time
islimitedbytheshortcircuitcurrentoftheLT1036andthe
load capacitance. A 10µF output capacitor slows the
output rise time to approximately 80µs.
The enable pin equivalent schematic is shown in Figure 3.
Basically, enable pin current is zero above the threshold
and about 1.5µA below the threshold, flowing out of the
pin. Standard logic, such as TTL and CMOS, will interface
directly to the enable pin, even if the logic output swing is
higher than the input voltage (VIN) to the regulator.
15V CMOS can be used to drive the enable pin, even if
the regulator is not powered up, without loading the
CMOS output.

Output Current
An additional feature of the LT1036 is that the auxiliary
supply does not incorporate, nor is it affected by, thermal
shutdown. Any fault condition of the main regulator will
not affect the auxiliary output voltage.
The main output current limits at about 4A for input
voltages below 20V. Internal foldback, or “power limit-
ing”, circuitry detects the input-output voltage differential
and reduces current limit for input to output voltages
exceeding 8V. With 25V input, for instance, short circuit
current is reduced to ≈ 0.9A.
The following applications circuits will serve to indicate
the versatility of the LT1036.
