What is MCP1824T-5002E/OT used for?
The MCP1824T-5002E/OT is ideal for powering 5 V microcontrollers and logic ICs from a single-cell Li-Ion or regulated 6 V bus in battery-operated handheld devices and IoT sensor nodes. Its low 200 mV dropout voltage ensures stable 5 V output even when the input sags near the end-of-charge level, extending battery runtime. Industrial designers also use it to derive a clean 5 V rail for op-amp biasing and ADC reference circuits within confined PCB areas.

Frequently Asked Questions
How low can the input voltage drop before the MCP1824T-5002E/OT loses regulation at 300 mA load?
At full 300 mA load the MCP1824T-5002E/OT maintains its 5.0 V output as long as the input voltage stays above approximately 5.2 V, given its 200 mV typical dropout voltage. The maximum dropout at full load is 320 mV, so a minimum input of 5.32 V is needed to guarantee regulation across all conditions.
Which sensor and microcontroller applications benefit most from the MCP1824T-5002E/OT shutdown feature?
Battery-powered IoT nodes that use a host MCU to gate peripheral power can assert the active-low SHDN pin to cut the 5 V rail to sensors, saving the regulator's 55 µA quiescent current and extending pack life in sleep modes. This is particularly useful in remote environmental monitors that wake, sample 8 or more sensors, and return to standby for minutes at a time.
What output capacitor is required for stable operation of the MCP1824T-5002E/OT, and does it accept ceramic types?
The MCP1824T-5002E/OT is stable with a minimum 1 µF ceramic output capacitor, making it cost-effective and space-efficient compared to LDOs requiring tantalum or electrolytic capacitors of 10 µF or more. Using a 4.7 µF X5R ceramic improves transient response during load steps up to 300 mA.
How does the MCP1824T-5002E/OT compare to the MCP1703 for a 5 V, 300 mA design needing shutdown control?
The MCP1824T-5002E/OT offers the same 300 mA current rating as the MCP1703A-5002 but adds an active-low shutdown pin that the MCP1703 lacks, enabling controlled power sequencing without an external MOSFET switch. Both share the SOT-23-5 package and accept ceramic output capacitors as small as 1 µF.
What is the absolute maximum input voltage the MCP1824T-5002E/OT can withstand without damage?
The absolute maximum input voltage for the MCP1824T-5002E/OT is 6.5 V; exceeding this risks permanent damage to the device. Normal continuous operation is specified up to 6 V, so a 300 mV margin is maintained between the rated operating maximum and the absolute limit, important for designs with noisy or unregulated supply rails.
