The Si9185 is a 500 mA CMOS low dropout (LDO) regulator that features low dropout and ground current in a compact, thermally enhanced MLP33 PowerPAK package. With low dropout of 150 mV at 500 mA, and a 3 × 3 mm footprint, the Si9185 is designed to prolong battery life in compact, portable electronics. The device is specified for input voltages from 2 V to 6 V and is available in 10 fixed voltage options ranging from 1.2 V to 5.0 V, as well as in adjustable output voltage options. The device features noise output of 100 microvolts (rms) with a noise bypass capacitor, 1.5% output voltage accuracy, 1.1 W power dissipation, and a maximum shutdown current of 1 microamp.
