LP3893ESX-1.2/NOPB

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

The LP3893ESX-1.2/NOPB is a fixed positive linear low-dropout regulator manufactured by Texas Instruments, providing a stable 1.2V output with a maximum current capacity of 3A. It operates within an input voltage range up to 5.5V and features a typical dropout voltage of 1V at 1A load. The device incorporates comprehensive protection mechanisms including overcurrent limiting, thermal shutdown, short-circuit protection, and undervoltage lockout. Designed for surface-mount installation in a TO-263 (DDPAK-5) package, it supports an operating temperature range from -40°C to +125°C.

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

Integrated protection circuitry ensures reliability through overcurrent limiting, thermal shutdown, and undervoltage lockout.
Fixed 1.2V output configuration provides precise voltage regulation without external feedback components.
High current capability allows delivery of up to 3A continuous output current for demanding loads.

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

Battery-powered systems requiring efficient power management
Portable consumer electronics with strict space constraints
Embedded control circuits needing stable low-voltage rails

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

Verify the complete part number including the suffix to ensure correct output voltage and packaging options. Confirm RoHS compliance status matches project requirements. Check moisture sensitivity level handling procedures during assembly. Validate that the TO-263 footprint aligns with the printed circuit board design specifications before finalizing procurement orders.

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

Select this component when a fixed 1.2V rail is required with high current demand up to 3A. Ensure the input voltage does not exceed the 5.5V maximum rating under all operating conditions. Consider the thermal performance of the TO-263 package if ambient temperatures approach the upper limit of the specified range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the LP3893 series of ultra-low-dropout linear regulators designed for high-efficiency applications. It shares architectural similarities with other members of the family but differs in specific output voltage settings and current ratings compared to variants like the LP3892 or LP3891.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

LP3893ESX-1.2/NOPB-ND serves as an alternative distributor-specific identifier for the same component. Verify pin compatibility and thermal characteristics when substituting with other LDO regulators offering similar 3A output capabilities.
