The MIC5317 is a high performance 150 mA low dropout regulator that offers high power supply rejection (PSRR) in an ultra-small 1mm x 1mm package for stringent space requirements and demanding performance. The MIC5317 operates from an input voltage from 2.5V to 6.0V and is capable of providing the output voltages of 1.0V to 3.6V making it ideal for USB port or 6V AC adapter applications.
The MIC5317 offers 2% initial accuracy, low dropout voltage (155 mV @ 150 mA), and low ground current (typically 29 μA). The MIC5317 can also be put into a zero off-mode current state, drawing virtually no current when disabled.
The MIC5317 is available in several advanced packages including a lead-free (RoHS-compliant) 1mmx1mmUDFNthatoccupiesonly1mm2ofPCB area, a 75% reduction in board area compared to SC-70 and 2 mm x 2 mm DFN packages. It is also available in a SOT23-5 and TSOT23-5 package.
The MIC5317 has an operating junction temperature range of –40°C to 125°C.
