It provides an easy-to-use power supply solution for PIC® microcontroller applications powered by either single-cell, two-cell, or three-cell alkaline, NiCd, NiMH, and single-cell Li-Ion or Li-Polymer batteries. Low-voltage technology allows the regulator to start up without high inrush current or output voltage overshoot from a low 0.65V input. High efficiency is accomplished by integrating the low-resistance N-Channel Boost switch and synchronous P-Channel switch. All compensation and protection circuitry are integrated to minimize external components. For standby applications, the MCP1624 operates and consumes only 19 µA while operating at no load. A “true” Load Disconnect mode provides input to output isolation while disabled (EN = GND) by removing the normal boost regulator diode path from input to output. This mode consumes less than 1 µA of input current. Output voltage is set by a small external resistor divider.
