The TPS22919DCKR is a single-channel, N-channel high-side load switch from Texas Instruments, rated for 1.5 A continuous output over a 1.6 V to 5.5 V load-voltage range. The 89 mOhm typical on-resistance keeps conduction loss under 200 mW at full load — well within the SC-70-6 package's thermal budget when the copper pad is sized per the datasheet layout.
Industrial temperature grade and environment
The 1.6 V minimum load voltage also covers the 1.8 V logic rails common in low-power MCU and FPGA designs.
The SC-70-6 package is a standard TI footprint, widely second-sourced for assembly.
