The MIC5318 is a high performance, single output, ultra-low dropout (ULDO™) regulator that offers low total output noise in an ultra-small Thin package. The MIC5318 is capable of sourcing 300mA output current and offers high PSRR and low output noise, making it a great solution for RF applications.
Ideal for battery-operated applications, the MIC5318 offers 2% initial accuracy, extremely low dropout voltage (110mV at 300mA), and low ground current (typically 85µA total). The MIC5318 can also be put into a zero off-mode current state, drawing no current when disabled.
The MIC5318 is available in the 1.6mm x 1.6mm Thin package, occupying only 2.56mm2 of PCB area, a 36% reduction in board area when compared to SC-70 and 2mm x 2mm packages.
The MIC5318 has an operating junction temperature range of -40°C to +125°C and is available in fixed and adjustable output voltages in lead-free (RoHS-compliant) Thin and Thin SOT23-5 packages.
