Frequently Asked Questions
What is the dropout voltage of the MCP1754ST-3302E/CB at maximum load current?
The MCP1754ST-3302E/CB has a nominal dropout voltage of 0.3 V and a guaranteed maximum of 0.5 V at full 150 mA output current. This low dropout allows the regulator to maintain the 3.3 V output even when the input supply drops to approximately 3.8 V, extending usable runtime in battery-powered applications.
Can the MCP1754ST-3302E/CB be used directly from a single-cell Li-ion battery, and what input range is supported?
The MCP1754ST-3302E/CB requires a minimum input of 3.6 V and supports up to 16 V, so a fully charged single-cell Li-ion battery (typically 4.2 V) is within its operating range. As the cell discharges toward 3.6 V, the low 0.5 V maximum dropout ensures the 3.3 V output remains regulated throughout most of the battery's usable capacity.
How does the SOT-23A package of the MCP1754ST-3302E/CB compare to larger LDO packages in terms of thermal management?
The 3-pin SOT-23A package of the MCP1754ST-3302E/CB is compact but has limited thermal dissipation compared to SOT-89 or TO-252 alternatives. At the maximum rated 150 mA output and high input-to-output voltage differentials, power dissipation in the package can raise junction temperatures toward the 125 °C upper limit, so designs with larger voltage drops at full load should size the application's copper pads or current budget carefully.
