AX6604/5

Dual Channel LDO Regulators with Enable



GENERAL DESCRIPTION

The AX6604/5 is a high accurately, low noise, high ripple rejection ratio, low dropout, dual

CMOS LDO voltage regulators with enable function. The EN function allows the output of

each regulator to be turned off independently, resulting in greatly reduced power

consumption.

The AX6604/5 has the soft start function to suppress the inrush current. The current

limit is over 250mA per channel and also operates as a short protection for the output

current limiter. The output voltage for each regulator is set independently by metal trimming.

The AX6604/5 is fully compatible with low ESR ceramic capacitors, reducing cost and

improving output stability. This high level output stability is maintained even during frequent

load fluctuations, due to the excellent transient response performance and high PSRR

achieved across a broad range of frequency. It is available in the SOT-23-6L package.
