LT1036

Logic Controlled Regulator

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

100% Thermal Burn-In on All Devices

■

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.

Power Operation

Memory Power Supply with Back-Up

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.
