Key Features
- Fixed 5 V output with 1.5 A continuous current capability and ultra-low 330 mV typical dropout voltage
- Wide input range from 5.7 V to 6 V (absolute max 6.5 V) with robust short-circuit and thermal-overload protection
- DDPAK-5 surface-mount power package provides excellent thermal dissipation up to 15 W with an exposed pad
Applications
The MCP1827-5002E/ET is designed for embedded systems requiring a stable 5 V rail from a 5.7–6 V source such as a USB or single-cell Li-ion charger output, delivering up to 1.5 A with minimal heat generation thanks to the 330 mV typical dropout. It is also used as a post-regulator filter stage after switching converters in industrial control boards and automotive accessory modules where low noise and fast transient response on the 5 V supply are critical.

Frequently Asked Questions
What output voltage and current does the MCP1827-5002E/ET deliver, and what is its dropout voltage?
The MCP1827-5002E/ET provides a fixed 5 V output at up to 1.5 A continuous load current. Its typical dropout voltage is only 330 mV, meaning the input can be as low as 5.33 V while maintaining regulation, which is important for battery-powered designs near end-of-charge.
How does the DDPAK-5 package help manage thermal dissipation in high-current 5 V regulator designs?
The DDPAK-5 package features an exposed metal tab that can be soldered directly to the PCB copper pour, enabling heat transfer away from the die without a bulky heatsink. At 1.5 A output with 330 mV dropout, power dissipation is roughly 0.5 W, well within the package's 15 W thermal rating, keeping junction temperature below 125°C in most ambient conditions.
What input voltage range is required to operate the MCP1827-5002E/ET reliably?
The part requires an input voltage between 5.7 V minimum and 6 V rated maximum, with an absolute maximum of 6.5 V. This narrow window suits designs powered from a regulated 6 V rail or a freshly charged NiMH pack, ensuring the 5 V output stays in regulation without overstressing the device.
When would an engineer choose the MCP1827-5002E/ET over an adjustable LDO for a 5 V supply?
A fixed-output device like the MCP1827-5002E/ET eliminates the 2-resistor divider network, reducing component count and removing the risk of output-voltage trim drift over temperature. In high-volume USB-powered accessories or set-top box power stages where 5 V is always the target, the fixed variant saves board space and simplifies production testing compared to an adjustable LDO requiring calibration.
