General Description
The MIC5304 is a low quiescent current, low dropout
regulator with selectable output voltage designed for
applications that require two levels of output voltage
regulation. The MIC5304 is an ideal solution for
programming memory cards as well as for conserving
power in portable applications. The MIC5304 is capable of
sourcing 150mA of output current while only consuming
24µA of operating current. This high performance LDO
offers fast transient response while still maintaining low
quiescent current levels.
The MIC5304 is an ideal solution for battery operated
applications due to ultra low operating current and
extremely low dropout voltage of 85mV at 150mA.
Equipped with a TTL logic compatible enable pin, the
MIC5304 can be put into a zero-off mode current state,
drawing virtually no current when disabled.
Board space and component cost is minimized because
the MIC5304 operates with very small 1μF ceramic
capacitors. The MIC5304 provides fixed output voltages,
and is available in the tiny 1.6mm x 1.6mm Thin MLF
®
package ideal for portable electronics.
MIC5304 also features thermal shutdown and current limit
protection.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.

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. Regulation is measured at constant junction temperature using low duty cycle pulse testing; changes in output voltage due to heating effects are
covered by the thermal regulation specification.
7. 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.
8. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin
current.
