DESCRIPTION

The LDRxxyy is a Very Low Drop Dual Voltage

Regulator available in PPAK for the version

without inhibit and in SPAK-7L for the version with

the shutdown feature. The very low drop-voltage

(0.5V) and the very low supply current make it

particularly suitable for low noise and low power

applications such as PDA, MICRODRIVE and

other data storage applications while the used

high

voltage

technology

makes

this

device

suitable

for

consumer

applications such

as

MONITORS AND SET-TOP-BOX. For each VO a

Shutdown Logic Control function is available (TTL

compatible)

to

decrease

the

total

power

consumption.
