MIC2951-03YM More Semiconductors - ICs by Microchip Technology
Improved LP2951 Low Drop-out Regulator
| Status: | Active |
|---|---|
| Series: | MIC2951 |
| RoHS: | Compliant |
The MIC2950 and MIC2951 are "bulletproof" micropower voltage regulators with very low dropout voltage (typically 40mV at light loads and 250mV at 100mA) and very low quiescent currents. Like their predecessors, the LP2950 and LP2951, the quiescent current of the MIC2950/MIC2951 increases only slightly in dropout, thus prolonging battery life. The MIC2950/MIC2951 are pin-for-pin compatible with the LP2950/LP2951, but offer lower dropout, lower quiescent current, reverse battery protection, and automotive load dump protection.
The key additional features and protection offered include higher output current (150mA), positive transient protection for up to 60V (load dump), and the ability to survive an unregulated input voltage transient of -20V below ground (reverse battery).
The plastic DIP and SOIC versions offer additional system functions such as programmable output voltage and logic-controlled shutdown. The 3-pin TO-92 MIC2950 is pin-for-pin compatible with the older 5V regulators.
These system functions also include an error flag output that warns of a low output voltage, which is often due to failing batteries on the input. This may also be used as a power-on reset. A logic-compatible shutdown input is also available that enables the regulator to be switched on and off. This part may also be pin-strapped for a 5V output or programmed from 1.24V to 29V with the use of two external resistors.
