MIC5353-2.8YMT TR
General Description
The MIC5353 is a high-performance, single-output, ultra-
low LDO (ULDO™) regulator, offering a low total output
noise of 30μV
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.

... Micrel, Inc. Applications Information Enable/Shutdown The MIC5353 comes with an active-high enable pin that allows the regulator to be disabled. Forcing the enable pin low disables the regulator and sends it into a “zero” off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output voltage ...
