LT1963AEQ-1.5

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

The LT1963AEQ-1.5 is a fixed-output low dropout regulator from the LT1963A series, manufactured by Analog Devices (formerly Linear Technology). It provides a stable 1.5V output with a maximum current capacity of 1.5A. The device features a typical dropout voltage of 340mV at full load and maintains an operating quiescent current of 1mA, which drops below 1µA in shutdown mode. It supports input voltages up to 20V and operates within a temperature range of -40°C to +125°C. The component is housed in a TO-263-5 (DDPAK-5) surface-mount package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Optimized for fast transient response with controlled quiescent current that does not rise during dropout conditions
• Low output noise performance suitable for sensitive RF power supply applications
• Integrated internal protection circuitry including reverse battery protection, current limiting, thermal limiting, and reverse current protection

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel provides genuine components with traceable manufacturing data. Confirm RoHS compliance status as historical batches may vary. Validate that the TO-263-5 package matches the target PCB footprint requirements before finalizing orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a 1.5A current capability and 1.5V fixed output are required alongside low noise characteristics. It is appropriate for designs needing fast transient response without the complexity of adjustable regulators. Consider the thermal dissipation capabilities of the TO-263-5 package relative to the expected power loss under load conditions.
