TPS77633DRG4 Equivalent & Substitute Parts

Part Overview

The TPS77633DRG4 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.3V output at 500mA. This device is classified as a Power Management (PMIC) component and features integrated protection mechanisms including over-current, over-temperature, and reverse polarity protection. The TPS77633DRG4 is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and production continuity. The active equivalent variant remains available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS77633DRG4 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration: Positive fixed 3.3V
• Output current capability: 500mA minimum
• Input voltage tolerance: Maximum 10V
• Voltage dropout specification: 0.29V @ 500mA
• Quiescent current: 125 µA
• Control features: Enable and Power Good functions
• Protection mechanisms: Over-current, over-temperature, and reverse polarity protection
• Package format: 8-SOIC with 0.154" (3.90mm) width
• Temperature operating range: -40°C to 125°C
• Regulatory compliance: ROHS3 compliant

The TPS77633DR qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, control features, protection characteristics, and package geometry. The primary distinction is product status and packaging format availability.
