LT1963AEQ-1.5#TRPBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT1963AEQ-1.5#TRPBF is a fixed-output linear regulator from the Analog Devices LT1963A series, housed in a 5-lead plastic DD-Pak package with tape and reel packaging. It provides a regulated output of 1.5V at up to 1.5A load current. The device operates over an extended temperature range of -40°C to +125°C. Key electrical specifications include a typical dropout voltage of 340mV at full load, a quiescent current of 1mA, and a shutdown current below 1µA. It features integrated protections against overcurrent, thermal overload, and reverse input/output conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the LT1963AEQ-1.5 handle reverse input voltage?

The device acts as if there is a diode in series with its input during reverse voltage events, preventing reverse current flow into the regulator and protecting both the device and the load.

What is the function of the SENSE pin on this fixed voltage model?

For fixed voltage versions like the LT1963AEQ-1.5, the SENSE pin serves as the input to the error amplifier. Connecting it directly to the OUT pin ensures optimal regulation by compensating for voltage drops across PCB traces.
