MIC5353 LDO Regulators

Microchip's MIC5353 LDO regulators offer a low total output noise of 30 μV RMS

Micrel's MIC5353 LDO RegulatorsMicrochip's MIC5353 is a high-performance, single-output, ultra-low LDO (ULDO™) regulator that offers a low total output noise of 30 μVRMS. The MIC5353 is capable of sourcing 500 mA output current and offers high-PSRR and low-output noise, making it an ideal solution for RF applications. The MIC5353 provides 2 percent accuracy, extremely low dropout voltage (160 mV at 500 mA), and low ground current (typically 90 μA), making it ideal for battery-operated applications as well. When disabled, the MIC5353 enters a zero-off-mode current state, thereby drawing almost no current.

The MIC5353 has an operating junction temperature range of -40°C to 125°C and is available in fixed and adjustable output voltages. It is available in the 1.6 mm x 1.6 mm Thin MLF® package, which occupies only 2.56 mm2 of PCB area and provides 36 percent reduction in board area compared to SC-70 and 2 mm x 2 mm Thin MLF® packages.
