MIC2951 Overview
Features The MIC2950 and MIC2951 are “bulletproof” micropower High accuracy 3.3, 4.85, or 5V, guaranteed 150mA voltage regulators with very low dropout voltage (typically output 40mV at light loads and 250mV at 100mA), and very low Extremely low quiescent current quiescent current. Like their predecessors, the LP2950 and Low-dropout voltage LP2951, the quiescent current of the MIC2950/MIC2951 Extremely tight load...
MIC2951 Key Features
- High accuracy 3.3, 4.85, or 5V, guaranteed 150mA voltage regulators with very low dropout voltage (typically output 40mV
- Extremely low quiescent current quiescent current. Like their predecessors, the LP2950 and
- Low-dropout voltage LP2951, the quiescent current of the MIC2950/MIC2951
- Extremely tight load and line regulation increases only slightly in dropout, thus pro-longing battery
- Use as regulator or reference the LP2950/LP2951, but offer lower dropout, lower
- Needs only 1.5µF for stability quiescent current, reverse battery, and automotive load dump protection
- Current and thermal limiting
- Unregulated DC input can withstand -20V reverse The key additional features and protection offered include battery and +
- Error flag warns of output dropout (reverse battery)
- Logic-controlled electronic shutdown The plastic DIP and SOIC versions offer additional system
MIC2951 Applications
- Automotive electronics that warns of a low output voltage, which is often due to
- Voltage reference failing batteries on the input. This may also be used as a
- Avionics power-on reset. A logic-patible shutdown input is also available which enables the regulator to be switched on and
- Cellular telephones off. This part may also be pin-strapped for a 5 V output, or
- Battery powered equipment programmed from 1.24 V to 29 V with the use of two
