ACE1117

1A Positive Voltage Regulators

Technology

Note1: Low duty cycle pulse testing with which T_Jremains unchanged.

2: The I_Qof ACE1117-1.5 is 1.2mA (Typ.)

3: The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input

Fixed Voltage Regulator

Application Hints

The typical Linear regulator would require external capacitors to ensure stability. However, ACE1117 is

designed in such a way that these external capacitor can be omitted if the PCB layout is tight and system

noise is not very high. For better transient and PSRR performance, the Input and Output capacitors are still

recommended.

Input Capacitor

An input capacitor of 10μF is recommended. Ceramic or Tantalum can be used. The value can be

increased without upper limit.
