DESCRIPTION
The A6303D series are highly precise, low noise positive voltage LDO regulators manufactured using CMOS processes. The A6303D achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor.
The A603D is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The current limiter’s foldback circuit also operates as a short protect for the output current limiter and the output pin. The EN function enables the output to be turned off, resulting in greatly reduced power consumption.
The A6303D is available in SOT-25, SC-70-5 and DFN4 (1x1) packages.
