This output voltage matches the core supply of many low-power Cortex-M MCUs and sensor ASICs, so it slots directly into a 3.3 V or Li-ion powered subsystem without an external divider. Above 100 kHz the rejection rolls off, so a low-ESR output cap is still needed for high-frequency noise. ## Package and board-fit constraints Housed in a TSOT-23-6 (also listed as SOT-23-6 Thin), the part occupies roughly 3×3 mm of board area. Surface-mount assembly with standard reflow profiles works; the package is MSL1-equivalent by construction, so no moisture bake is needed before soldering if the shelf life is observed. ## Protection and control for unattended gear Built-in over-current, over-temperature, and short-circuit protection let the LDO survive a faulted load without latching off or requiring an external current-limit resistor. The Enable pin allows the downstream rail to be sequenced — useful in multi-rail systems where the core must come up after the I/O supply. The 140 µA quiescent current is moderate for a 300 mA LDO — not suited for always-on battery nodes, but fine for peripherals that spend most of their time in a shutdown state via the Enable pin.","metaTitle":"MAX1976AEZT150+T LDO 1.5V 300mA TSOT-23-6","metaDescription":"Analog Devices MAX1976AEZT150+T fixed 1.5V LDO regulator, 300mA output, 70dB PSRR, TSOT-23-6 package.
