The 10-TDFN exposed-pad package (3x3 mm body) aids thermal conduction to the PCB ground plane. ## Protection and control features Built-in overcurrent, overtemperature, and reverse-polarity protection cover the common fault conditions in point-of-load designs. An enable pin allows the regulator to be sequenced or shut down for power savings. The 2 mA quiescent current is typical for a 1A LDO with this protection suite — not a micropower part, but acceptable for always-on rails where the load current dominates the power budget. ## Lifecycle and sourcing posture The MAX38903BATB+ carries an active lifecycle status and ROHS3 compliance. For BOM planning, this part is suitable for both new designs and ongoing production.","metaTitle":"MAX38903BATB+ LDO Regulator, 1A, 0.6V-5V, 10-TDFN, PSRR 70dB","metaDescription":"MAX38903BATB+ LDO voltage regulator: 1A output, programmable 0.6V to 5V, PSRR 70dB at 1kHz, dropout 0.3V at 1A, -40°C to 125°C, 10-TDFN.
