MIC5310
Dual 150mA µCap LDO in 2mm x 2mm MLF
®
General Description
The MIC5310 is a tiny Dual Ultra Low Dropout
(ULDO™) linear regulator ideally suited for portable
electronics due to its high power supply ripple
rejection (PSRR) and ultra low output noise. The
MIC5310 integrates two high-performance 150mA
ULDOs into a tiny 2mm x 2mm leadless MLF
®
package, which provides exceptional thermal package
characteristics.
The MIC5310 is a µCap design which enables
operation with very small ceramic output capacitors
for stability, thereby reducing required board space
and component cost. The combination of extremely
low-drop-out voltage, high power supply rejection and
exceptional thermal package characteristics makes it
ideal for powering RF/noise sensitive circuitry, cellular
phone camera modules, imaging sensors for digital
still cameras, PDAs, MP3 players and WebCam
applications
The MIC5310 ULDO™ is available in fixed-output
®
voltages in the tiny 8-pin 2mm x 2mm leadless MLF
package which occupies less than half the board area
of a single SOT-6 package. Additional voltage options
are available. For more information, contact Micrel
marketing department.

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation of any T
A
(ambient temperature) is P
D(max)
= (T
J(max)
– T
A
) /
θ
JA
. Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
5. Specification for packaged product only.
6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal V
OUT
. For outputs below
2.3V, the dropout voltage is the input-to-output differential with the minimum input voltage 2.3V.
