General Description
The MIC5318 is a high performance, single output
ultra-low dropout regulator, offering low total output
noise in an ultra-small UDFN 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 (110 mV @ 300 mA), and low ground current
(typically 85 µA 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 1.6 mm x 1.6mm
UDFN package, occupying only 2.56 mm
2of PCB
area, fully a 36% reduction in board area when
compared to SC-70 and 2mm x 2mm UDFN
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) UDFN and Thin SOT23-5 packages.
