Substitute Part Grouping Explanation

Substitution eligibility for the TPS70802PWPR is determined by strict parametric equivalence across the following critical criteria:

Electrical Parameters: Output configuration (positive), output type (adjustable), number of regulators (2), input voltage maximum (6V), output voltage range (1.22V to 5.5V), dropout voltage (0.14V @ 250mA), output current ratings (250mA and 125mA), quiescent current (230 µA), PSRR performance (60dB @ 1KHz), control features (enable, power good, reset, sequencing), and protection features (over-current, over-temperature, reverse polarity, UVLO).

Mechanical Parameters: Surface mount mounting type, 20-PowerTSSOP package with 0.173" width (4.40mm), and 20-HTSSOP supplier device package.

Compliance Parameters: ROHS3 compliance, MSL rating of 2 (1 Year), and REACH unaffected status.

The TPS70702PWPR meets all parametric requirements for substitution. The primary distinction is product status: TPS70802PWPR is obsolete while TPS70702PWPR is active, making the latter the recommended alternative for new designs and ongoing supply requirements.
