MIC5335
Dual, High Performance 300mA µCap
ULDO^TM
General Description
The MIC5335 is a high current density, dual Ultra Low
Dropout (ULDO™) linear regulator. The MIC5335 is
ideally suited for portable electronics which demand
overall high performance in a very small form factor.
The MIC5335 is offered in the ultra small 1.6mm x
1.6mm 6-ld Thin MLF^® package which is only
2.56mm² in area of the SOT-23, TSOP and the 3mm x
3mm MLF^® package. The MIC5335 delivers
exceptional thermal performances for those
applications that demand higher power dissipation
requirements in a very small foot print. In addition, the
MIC5335 integrates two high performance 300mA
LDOs with independent enable functions and offers
high PSRR eliminating the need for a bypass
capacitor.
The MIC5335 is a µCap design which enables
operation with very small output capacitors for
stability, thereby reducing required board space and
component cost.
The MIC5335 is available in fixed-output voltages.
Additional voltages are available. For more
