MIC5363/4
High-PSRR, 300mA, µCap LDO
in 1.2mm × 1.2mm Thin MLF^®
General Description
Features
The MIC5363/4 is an advanced, 300mA LDO ideal for
powering general purpose portable devices requiring a
high power supply rejection ratio (PSRR). The MIC5363/4
integrates a high-performance, 300mA LDO into a tiny
1.2mm x 1.2mm Thin MLF^® package.
The MIC5363/4 is designed to reject input noise and
provide a low output noise regulator with fast transient
response to respond to any load change quickly. The
MIC5364 also incorporates an active discharge feature
that switches a 30Ω NFET from VOUT to GND to
discharge output capacitors when the part is disabled.
The MIC5363/4 is available in fixed output voltages in
lead-free (RoHS-compliant) 6-pin 1.2mm x 1.2mm Thin
MLF^® leadless package.
