General Description
MIC5318 General Description
The MIC5318 is a high performance, single output ultra low drop-out (ULDO™) regulator, offering low total output noise in an ultra-small Thin MLF® package. The MIC5318 is capable of sourcing 300mA output current and offers high PSRR and low output noise, making it an ideal solution for RF applications. Ideal for battery operated applications, the MIC5318 offers 2% initial accuracy, extremely low dropout voltage (110mV @ 300mA), and low ground current (typically 85A 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 MLF® package, occupying only 2.56mm2 of PCB area, fully a 36% reduction in board area when compared to SC-70 and 2mm x 2mm MLF® 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 MLF® and Thin SOT23-5 packages.
