RS1117A

1.0A Low Dropout Positive Voltage Regulator

DESCRIPTION

FEATURES

The RS1117A is a 1A low-dropout positive voltage

regulator. It is available in fixed and adjustable output

voltage versions. Over current and thermal protection

are integrated onto the chip. Output current will limit

as while it reaches the pre‐set current or temperature

limit. The dropout voltage is specified at 1.40V

Maximum at full rated output current. The RS1117A

series provides excellent regulation over line, load

and temperature variations.



Low Dropout Voltage 1.40V (Max.) at 1.0A

Adjustable or Fixed Voltage (1.8V, 2.5V, 3.3V,

5.0V)



Over Current Protection

Thermal Overload Protection

Maximum Line Regulation 0.2%

Maximum Load Regulation 1.0%

Adjust Pin Current Less Than 120μA

APPLICATIONS
