Microchip Technology, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MIC2951-4.85BM

The MIC2951-4.85BM is a low-dropout voltage regulator capable of delivering up to 150mA output current. It features a guaranteed output voltage of 4.85V with high accuracy and extremely low quiescent current, making it suitable for battery-powered applications. The device has a low dropout voltage, typically around 250mV at 100mA, and offers tight load and line regulation, ensuring stable performance across varying input conditions. This regulator is designed to withstand unregulated DC input voltages, including reverse battery conditions of -20V and positive transients up to +60V. It includes additional features such as current and thermal limiting, an error flag for output dropout indication, and a logic-controlled shutdown function. The MIC2951 can be used in various applications, including automotive electronics, avionics, and as a voltage reference in high-efficiency linear power supplies. The device requires only 1.5µF for stability, simplifying design requirements.
