The MIC5203-4.0BM4 TR is a low-dropout linear voltage regulator designed to provide a stable output of 4.0V with a maximum output current of 80mA. It features a very low dropout voltage, typically 20mV at light loads and 300mV at full load, which enhances its efficiency in battery-powered applications. The device operates with a low quiescent current of 225µA at 20mA output, making it suitable for energy-sensitive designs. This regulator is optimized for use with low-value, low-cost ceramic capacitors, requiring only 0.47µF of output capacitance for stability. It includes features such as current limiting, overtemperature shutdown, and protection against reversed battery connections. The MIC5203 can be enabled or disabled via a TTL/CMOS compatible logic signal, allowing for flexible control in various applications. The MIC5203-4.0BM4 TR is suitable for a range of applications including cellular phones, laptops, battery-powered devices, and barcode scanners. It is available in compact SOT-143 and SOT-23-5 packages, making it a versatile choice for space-constrained designs.
