General Description

The ECL1121 series are precise, low power consumption, high voltage; positive voltage regulators manufactured
using CMOS and laser trimming technologies.
The series provides large currents with a significantly small dropout voltage.
The ECL1121 consists of a current limiter 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 feedback 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 within a range of 1.2V to 5.0V.
SOT89, SOT23-3L, SOT-353 and SOT23-3B packages are available.
