MCP1826S-3302E/EB

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MCP1826S-3302E/EB is a fixed-output linear voltage regulator from Microchip Technology, providing a stable 3.3V output with a maximum current capacity of 1A. It operates within an input voltage range of 2.3V to 6V and features a typical dropout voltage of 250mV at full load. The device maintains a low quiescent current of 220µA and offers high power supply rejection ratio (PSRR) of 60dB at 100Hz. Designed for automotive applications, it meets AEC-Q100 standards and functions reliably across an extended temperature range of -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix EB indicates the DDPAK-3 package configuration when sourcing. Confirm AEC-Q100 compliance requirements match your system's automotive grade specifications. Ensure input voltage does not exceed the 6V absolute maximum rating to prevent device damage. Check for RoHS and REACH compliance documentation if required by your manufacturing standards.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.3V rail is needed with 1A capability in an automotive context. Compare dropout voltage characteristics against other LDOs if headroom is limited. Consider the thermal performance of the DDPAK package for heat dissipation needs. Verify that the 220µA quiescent current meets the standby power constraints of the application design.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MCP1826 family of high-current low-dropout regulators.
