Description
ACE507A
Precise Low Dropout Voltage Regulator
The ACE507A series are precise, low power consumption, positive voltage regulators manufactured
using CMOS and laser trimming technologies. The series provides large currents with a significantly small
dropout voltage. The ACE507A consists of a current limit circuit, a driver transistor a precision reference
voltage and an error correction circuit. The series is compatible with low ESR ceramic capacitors. The
current limiter’s foldback circuit also operates as a short protect for the output current limiter and the
output pin. Output voltage can be set internally by laser trimming technologies. It is selectable in 100mV
Increments with a range of 1.2V to 5.0V. SOT-89-3 and SOT-23-3 packages are available.
