Substitute Part Grouping Explanation
Substitution of the TPS70102PWPRG4 is determined by strict equivalence across the following critical parameters:
- Output configuration (Positive)
- Output type (Adjustable)
- Number of regulators (2)
- Maximum input voltage (6V)
- Output voltage range (1.22V to 5.5V)
- Current delivery per output (500mA, 250mA)
- Voltage dropout specification (0.28V @ 500mA)
- Quiescent current (190 µA)
- PSRR performance (60dB @ 1kHz)
- Control and protection feature set
- Operating temperature range (-40°C ~ 125°C)
- Package type (20-PowerTSSOP)
The TPS70202PWPR meets all these criteria and qualifies as a parametric equivalent substitute.
