MIC5317-1.8YMT-TZ

A high performance 150 mA low dropout regulator that offers high power supply rejection (PSRR) in an ultra-small 1 mm × 1 mm package for stringent space requirements and demanding performance. It operates from an input voltage from 2.5 V to 6.0 V and is capable of providing the output voltages of 1.0 V to 3.6 V, making it ideal for USB port or 6V AC adapter applications. It offers 2% initial accuracy, low dropout voltage (155 mV @ 150 mA), and low ground current (typically 29 μA). It can be put into a zero off - mode current state, drawing virtually no current when disabled. It is available in several advanced packages including a lead - free (RoHS - compliant) 1 mm × 1 mm UDFN that occupies only 1 mm² of PCB area, a 75% reduction in board area compared to SC - 70 and 2 mm × 2 mm DFN packages. It also comes in a SOT23 - 5 and TSOT23 - 5 package. It has an operating junction temperature range of - 40°C to 125°C.
