MIC5353
500mA LDO in 1.6mm 1.6mm Package
General Description Features
The MIC5353 is a high-performance, single-output, ultra-
500mA guaranteed output current
low LDO (ULDO) regulator, offering a low total output
Input voltage range: 2.6V to 6V
noise of 30 V . The MIC5353 is capable of sourcing
RMS
Ultra low dropout voltage: 160mV @ 500mA
500mA output current and offers high-PSRR and low-
2% initial accuracy
output noise, making it an ideal solution for RF
applications. Ultra low output noise: 30Vrms
The MIC5353 provides 2% accuracy, extremely low Low quiescent current: 90A
dropout voltage (160mV @ 500mA), and low ground
Stable with ceramic output capacitors
current (typically 90A) making it ideal for battery-operated
35s turn-on time
applications. When disabled, the MIC5353 enters a zero-
Thermal shutdown and current limit protection
off-mode current state, thereby drawing almost no current.
Tiny 6-pin 1.6mm x 1.6mm Thin MLF leadless package
The MIC5353 is available in the 1.6mm x 1.6mm Thin
2
MLF package, occupying only 2.56mm of PCB area, a
36% reduction in board area compared to SC-70 and 2mm
Applications
x 2mm Thin MLF packages.
Mobile Phones
The MIC5353 has an operating junction temperature range
GPS, PDAs, PMP, handhelds
of 40C to +125C and is available in fixed and adjustable
output voltages in lead-free (RoHS-compliant) Thin MLF Portable electronics
package.
