Micrel MIC29512BT L3

Overview

The MIC2950 and MIC29512BT 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/MIC29512BT increases only slightly in dropout, thus prolonging battery life. The MIC2950/MIC29512BT are pin-for-pin compatible with the LP2950/LP2951, but offer lower dropout, lower quiescent current, reverse battery protection, and automotive load dump protection.

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.
