The TPS3838L30DBVR is a single-channel voltage supervisor from Texas Instruments, monitoring a 2.64 V threshold with an active-low, open-drain reset output.
The SOT-23-5 (SC-74A) package shares the same 0.95 mm pitch as many other TI supervisors, so a layout designed for the TLV803 family will accept this footprint with no board change.
The part is ROHS3 compliant.
The reset timeout is 10 ms minimum. After the supply rises above the threshold, the supervisor holds reset low for at least 10 ms before releasing it.
The TLV803EA29VDBZR is a close parametric match: same active-low open-drain output, same SOT-23-5 package, but with a 2.93 V threshold and a 130 ms minimum reset timeout. The TLV803ED29DBZR offers a 33 ms timeout. Neither is a drop-in replacement — the threshold and timeout differences must be verified against the processor's brown-out requirements.
