ME1117
1.0A Adjustable Voltage High Speed LDO Regulators ME1117 Series
General Description
The ME1117 series are highly accurate, low noise,
LDO Voltage Regulators that are capable of
providing an output current that is in excess of 1.0 A
with a maximum dropout voltage of 1.3 V at 1.0A.
This series contains six fixed output voltages of 1.2
V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V that have no
minimum load requirement to maintain regulation.
Also included is an adjustable output version that can
be programmed from 1.25 V to 15 V with two
external resistors. On chip trimming adjusts the
reference/output voltage to within ±2.0% accuracy.
Internal protection features consist of output current
limiting, safe operating area compensation, and
thermal shutdown. The ME1117 series can operate
with up to 15 V input. Devices are available in
SOT223,TO252-2L .
