• Manufacturer Part Number: ace1117c
• Description: 1a Bipolar Linear Regulator
• Manufacturer: ACE Technology Co., LTD.

Note1: The Parameters of Line Regulation and Load Regulation in Table1 are tested under constant junction temperature. The
Note2: When Iout varies between 0~1A,Vin-Vout varies between 1.5V~12V under constant junction temperature，the parameter
Note3: Dropout Voltage is specified over the full output current range of the device, and it is tested under following testing
Note4: Minimum Load Current is defined as the minimum output current required to maintain regulation. When 1.5V≦Vin-Vout≦

12V,the device is guaranteed to regulate if the output current is greater than 10mA.
Curve of Load Regulation vs. Temperature is shown in typical parameter curve that follows.
is satisfied the criterion in table. If temperature varies between -40℃≤TA≤85℃，it needs output current to be larger than
10mA to satisfy the criterion.
conditions: First step is to find out the Vout value(Vout1) when Vin1=Vout+1.5V, second step is to decrease Vin(Vin2) until
Vout value is equal to 98.5%*Vout1(Vout2). Vdropout=Vin2-Vout2.
