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

PPAK
(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.
