Key Features

  • Fixed 3.3 V output with up to 1.5 A output current and only 330 mV typical dropout voltage, enabling efficient regulation from 4.5 V or 5 V rails
  • CMOS LDO architecture delivering very low quiescent current, extending battery runtime in portable and IoT applications
  • DDPAK-3 power package with exposed pad for enhanced thermal dissipation, supporting continuous 1.5 A loads without excessive heatsinking

Applications

The MCP1827S-3302E/EB is ideal for post-regulation in 5 V USB-powered systems, microcontroller supply rails, and IoT sensor nodes where a stable 3.3 V at up to 1.5 A is required with minimal dropout. Its low quiescent current and CMOS architecture make it well-suited for battery-powered handheld devices and wireless modules that demand extended runtime. The DDPAK-3 package provides sufficient thermal headroom for continuous full-load operation in compact industrial and consumer designs.

Frequently Asked Questions

What is the dropout voltage of MCP1827S-3302E/EB, and how does it affect minimum input supply requirements?

The MCP1827S-3302E/EB has a typical dropout voltage of 330 mV and a maximum of 600 mV at 1.5 A load. This means the minimum input voltage needed to maintain the regulated 3.3 V output is approximately 3.97 V under worst-case conditions, making it directly compatible with single-cell Li-ion batteries and 4.5 V to 6 V regulated supplies.

How much output current can MCP1827S-3302E/EB supply, and which load scenarios suit its DDPAK-3 package?

The MCP1827S-3302E/EB is rated for up to 1.5 A continuous output current. The DDPAK-3 package includes an exposed thermal pad that efficiently conducts heat to the PCB, making it suitable for powering microprocessors, FPGAs, and multi-channel sensor arrays that draw sustained currents in the 500 mA to 1.5 A range in industrial and communications equipment.

Why is MCP1827S-3302E/EB a strong choice for 5 V USB-to-3.3 V power conversion compared to a switching regulator?

For 5 V USB input to 3.3 V output conversion with loads under 1.5 A, the MCP1827S-3302E/EB offers a simpler, lower-noise solution than a switching regulator because it requires no inductor and produces no switching noise. The 1.7 V input-to-output differential is well within the 600 mV maximum dropout specification, allowing full 1.5 A output from a 5 V rail with only a few bypass capacitors needed externally.

What input voltage range does MCP1827S-3302E/EB support, and does it comply with RoHS requirements for modern product designs?

The MCP1827S-3302E/EB accepts input voltages from 3.97 V minimum to 6 V maximum, with an absolute maximum of 6.5 V. The device is fully RoHS-compliant (Pb-free), meeting EU Directive 2011/65/EU requirements, which is essential for consumer electronics and industrial equipment sold in regulated markets worldwide.
