Micrel MIC5317 LDOs

Micrel MIC5317 LDOs are high performance 150mA low dropout regulators offering high power supply rejection (PSRR) in an ultra-small 1mm × 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 adaptor applications. The MIC5317 offers 2% initial accuracy, low dropout voltage (155mV @ 150mA), and low ground current (typically 29µA). 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) 1mm × 1mm Thin DFN occupying only 1mm2 of PCB area, a 75% reduction in board area compared to SC-70 and 2mm × 2mm 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.
