Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for LP2954IT

LP2954IT

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

The LP2954IT is a micropower low-dropout voltage regulator manufactured by Texas Instruments, housed in a TO-220 package. It provides a fixed 5V output with an accuracy of ±1.2% over the operating temperature range. The device supports up to 250 mA of output current and features extremely low quiescent current, typically 90 μA at 1 mA load and 120 μA during dropout. It operates within an input voltage range of -20 V to +30 V and maintains operation across a junction temperature range of -40°C to +125°C.

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

Extremely low quiescent current that increases only slightly during dropout conditions
Reverse battery protection capability for input supply safety
Tight line and load regulation suitable for use as a low-power voltage reference
Integrated thermal limiting and current limiting protection

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

High-efficiency linear regulator circuits
Low dropout battery-powered systems
Low-power voltage reference applications

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

Verify the specific suffix 'IT' corresponds to the TO-220 package and industrial temperature grade (-40°C to +125°C). Confirm RoHS compliance status, as non-NOPB versions may differ from lead-free specifications. Ensure the source documentation explicitly lists LP2954IT as an active or available part number before procurement planning.

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

Select this component when a fixed 5V output is required with minimal ground current consumption. The TO-220 package facilitates through-hole mounting and heat dissipation. Verify that the application does not require the adjustable version's error flag or shutdown features, which are exclusive to the SOIC-8 pin-strapped variants.

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

This device belongs to the LP2954/LP2954A family of micropower regulators. It is pin-compatible with LM2940 and LM340 devices (5V version only), allowing for potential direct replacements in existing designs requiring similar form factors and fixed voltage outputs.
