General Description

The MIC5353 is a high-performance, single-output, ultra-

low LDO (ULDO™) regulator, offering a low total output

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

36% reduction in board area compared to SC-70 and 2mm

x 2mm Thin MLF

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.
