Linear & Switching Voltage Regulators

MCP1826S-3302E/EB Description

The MCP1826S-3302E/EB from Microchip Technology is a high-performance, fixed-output 3.3V, 1A low-dropout (LDO) linear voltage regulator designed for demanding power management applications. Housed in a 3DDPAK surface-mount package, this regulator delivers stable power with a low dropout voltage of 0.4V @ 1A, making it ideal for systems with tight voltage margins. Its 60dB PSRR (100Hz) ensures excellent noise rejection, while a quiescent current of 220 µA enhances efficiency in battery-operated devices. The device is RoHS3 compliant and features robust protection mechanisms, including over-temperature, short-circuit, and UVLO (Under Voltage Lockout), ensuring reliable operation in harsh environments.
