LP2980IM5-3.2/NOPB Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The LP2980IM5-3.2/NOPB is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.2V output applications with 50mA current capacity in a compact SOT-23-5 surface mount package. This device is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, production continuity, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP2980IM5-3.2/NOPB is determined by the following critical parameters:

• Fixed output voltage of 3.2V
• SOT-23-5 package compatibility
• Operating temperature range of -40°C to 125°C
• Enable control feature
• Over current and over temperature protection
• ROHS3 compliance and REACH unaffected status

The MIC5206-3.2YM5-TR from Microchip Technology meets these core substitution criteria. While the substitute part offers higher output current capacity (150mA vs. 50mA) and additional features, it maintains electrical and mechanical compatibility with the original design when current requirements do not exceed the original specification.

Parameter Comparison

Engineering Selection Recommendations

The MIC5206-3.2YM5-TR is the designated substitute for the obsolete LP2980IM5-3.2/NOPB based on the following factors:

• Both devices maintain identical fixed output voltage (3.2V) and package configuration (SOT-23-5)
• Both operate across the full -40°C to 125°C temperature range
• Both comply with ROHS3 and REACH requirements
• The substitute part carries active product status, ensuring long-term availability and supply chain continuity
• The substitute part provides higher output current capacity (150mA), which does not compromise designs operating within the original 50mA specification
• Both devices include enable control functionality and core protection features (over current and over temperature)

Frequently Asked Questions (FAQ)

Q: Can the MIC5206-3.2YM5-TR directly replace the LP2980IM5-3.2/NOPB in existing designs?

A: Yes, the MIC5206-3.2YM5-TR is pin-compatible and functionally equivalent for applications requiring 50mA or less output current. Both devices use the SOT-23-5 package with identical pinout and control features.

Q: What are the key differences between these two regulators?

A: The primary differences are output current capacity (50mA vs. 150mA), dropout voltage specifications (0.22V vs. 0.35V at rated current), quiescent current (95 µA vs. 150 µA), and protection features. The substitute includes reverse polarity protection and an error flag output.

Q: Is the higher output current of the substitute part a concern for my application?

A: No. Higher output current capacity does not negatively impact designs. If your application requires 50mA or less, the substitute part operates within its safe operating region.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and rated for the same operating temperature range. No compliance differences exist between the two devices.

Q: What is the significance of the substitute part's active product status?

A: Active product status indicates the MIC5206-3.2YM5-TR is in current production with established supply chains and long-term availability. This contrasts with the obsolete status of the original part, which may face sourcing difficulties.

Q: Are there any thermal or power dissipation considerations when substituting?

A: Both devices are housed in the same SOT-23-5 package. Thermal performance depends on application-specific factors such as input-output voltage differential and load current, which remain unchanged when substituting within the 50mA specification.
