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 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
MLF
fully a 36% reduction in board area when compared to
SC-70 and 2mm x 2mm MLF
The MIC5318 has an operating junction temperature
range of –40°C to +125°C and is available in fixed and
adjustable
compliant) Thin MLF
