Micrel, Inc. PMIC - PMIC - Voltage Regulators - Linear - MIC5203-3.6BM5 MIC5203-3.6BM5

The MIC5203-3.6BM5 is a low-dropout linear voltage regulator designed to provide a fixed output voltage of 3.6V 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 makes it suitable for battery-powered applications. The device operates with a low quiescent current of 225µA at a 20mA output, contributing to extended battery life. 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 power management. It is available in a compact SOT-23-5 package and is suitable for various applications, including cellular phones, laptops, and portable devices.
