MIC5353
500mA LDO in 1.6mm × 1.6mm Package
General Description
The MIC5353 is a high-performance, single-output, ultra-
low LDO (ULDO™) regulator, offering a low total output
noise of 30μV_RMS. The MIC5353 is capable of sourcing
500mA output current and offers high-PSRR and low-
output noise, making it an ideal solution for RF
applications.
The MIC5353 provides 2% accuracy, extremely low
dropout voltage (160mV @ 500mA), and low ground
current (typically 90µA) making it ideal for battery-operated
applications. When disabled, the MIC5353 enters a zero-
off-mode current state, thereby drawing almost no current.
The MIC5353 is available in the 1.6mm x 1.6mm Thin
MLF^® package, occupying only 2.56mm² of PCB area, a
36% reduction in board area compared to SC-70 and 2mm
x 2mm Thin MLF^® packages.
The MIC5353 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^®
package.
