General Description
The MIC5316 is a high performance, dual low input
voltage, low dropout regulator with Power On Reset (POR)
and voltage select. Major features include two 300mA
LDOs, input voltage down to 1.7V, ultra low drop out of
85mV at full load, Power on Reset, and voltage select.
Each LDO has its own low voltage input for system
flexibility. The low input voltages and low drop out
operation provides high efficiency by reducing the input to
output voltage step which minimizes the regulator power
loss. Voltage select is incorporated into the second output,
which reduces the output voltage to further save power
while in stand-by mode. An adjustable delay time POR
output is provided for the second regulator for design
flexibility.
Ideal for battery operated applications; the MIC5316 offers
1% accuracy and low ground current to increase light load
efficiency. The MIC5316 can also be put into a zero-off-
mode current state, drawing virtually no current when
disabled.
The MIC5316 is available in fixed output voltages in the
12-pin 2.5mm x 2.5mm Thin MLF
