AMS1117(L)
1A Adiustable / Fixed Low Dropout Linear Requlator
Description
Features
The AMS1117 is a series of low dropout voltage Low Dropout Voltage
regulators which can provide up to 1A of output Load regulation:0.5% Max
current. The AMS1117 is available in six fixed Optimized for Low Voltage
voltage, 1.2, 1.8, 2.5, 3.3 and 5.0V. Additionally it is On-chip thermal limiting.
also available in adjustable version. On chip Maximum Input Voltage : 30V
precision trimming adjusts the reference/ output Adjustable Output Voltage or Fixed 1.2V, 1.8V,
voltage to within ± 2%. On-chip thermal limiting
provides protection against any combination of
overload and ambient temperatures that would
create excessive junction temperatures.
IP The AMS1117 series is available in SOT-223,
TO-252, SOT89 packages. A minimum of 10uF
tantalum capacitor is required at the output to
H improve the transient response and stability.
