Detailed Description

ACE1084 is a series of low dropout voltage three terminal regulators. Its circuit has a trimmed band gap

reference to ensure output voltage accuracy independent of temperature variance. On-chip thermal

shutdown provides protection against overload and conditions as elevated ambient temperature.

Its application circuitry requires minimum number of external components. Both fixed voltage and

adjustable voltage versions need input and output capacitors to assure output voltage stability. Any

desired output voltage from 1.25V to 10V can be achieved with adjustable version by assigning proper

values to two external resistors in its application circuitry (as shown in Figure.1, as R1, R2 are the two

external resistors.).

Typical Application

ACE1084 has an adjustable version and fixed versions, Figure.1 shows their typical application circuitry.

A 10uF tan capacitor connected between input and GND as bypass capacitor and a 22uF tan capacitor

between output and GND are recommended for all application.

bypass capacitor prevents ripple from being amplified in case the output voltage is increased. The

frequency. As R1 is normally in the range of 120Ω~200Ω, the value of C

condition:

1/(2π* Frequency

A 10µF tan capacitor is recommended.
