MIC5219 LDO Regulator
●General Description
▲The MIC5219 is an efficient linear voltage regulator with high peak output current capability, very low dropout voltage, and better than 1% output voltage accuracy. Dropout is typically 10 mV at light loads and less than 500 mV at full load.
▲The MIC5219 is designed to provide a peak output current for start-up conditions where higher inrush current is demanded. It features a 500 mA peak output rating. Continuous output current is limited only by package and layout.
▲The MIC5219 can be enabled or shut down by a CMOS- or TTL-compatible signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to help prolong battery life. Other key features include reversed-battery protection, current limiting, over temperature shutdown, and low noise performance with an ultra-low noise option.
▲The MIC5219 is available in adjustable or fixed output voltages in the space-saving 6-pin (2 mm × 2 mm) VDFN, 6-pin (2 mm × 2 mm) Thin DFN, SOT23-5, and 8-pin power MSOP packages. For higher power requirements see the MIC5209 or MIC5237
