The MIC5332-SSYMT-TR is a dual 300 mA ultra-low-quiescent-current ULDO (Ultra Low Dropout) regulator from Microchip in a compact 2 mm x 2 mm Thin MLF-8 package. Both LDO outputs are fixed at 3.3 V with +\/-1% accuracy. Drawing only 25 μA per LDO, it achieves PSRR >65 dB and 50 μVrms output noise. LDO2 integrates a Power-On Reset (POR) output with programmable delay via an external capacitor, eliminating the need for a separate reset IC.<\/p>\n

Each LDO contains a bandgap reference, error amplifier, and P-channel MOSFET pass element. CMOS process ensures very low ground current (25uA typ per LDO) that does not increase significantly with load. LDO2 integrates a POR comparator monitoring its output voltage; when output reaches threshold, POR2 goes high. CSET2 capacitor programs the POR delay (1sec\/uF); open = zero delay. Current limit and thermal shutdown provide fault protection.","pin_description":"
