5.0 VOLT ULTRA LOW DROPOUT
REGULATOR
ISSUE 1- DECEMBER 1995
ZLD0500
The ZLDO Series low dropout linear regulators
operate with an exceptionally low dropout
voltage, typically only 30mV with a load
current of 10OmA. The ragulatorseries features
output voltages in the range 3.3 to 18 volts, this
device provides an output voltage of 5.0 volts.
The ZLD0500 consumes a typical quiescent
current of only 630pA and is rated to supply
load currents up to 300mA. A battery low flag
is available to indicate potential power fail
situations. If the input voltage falls to within
300mV of the regulated output voltage then the
error output pul Is low. The device also featu res
an active high disable control. Once disabled
the ZLDO quiescent current falls to typically
Ii@.
The ZLDO devices are packaged in Zetex SM8
8 pin small outline surface mount package,
ideal for applications where space saving is
important. The device low dropout voltage,
low quiescent current and small size make it
ideal for low power and battery powered
applications. Battev powered circuits can
make particular use of the low batte~ flag and
shutdown features.

APPLICATIONS
transistor which pulls low when the supply to the
regulator is failing. Fig.3 shows this output Wing
used. Note that resistor RI is neceese~ only if
the intarrupt logic does not include a pull-up
resistor.
4). Distributed Power Supplies
A common problem with large multiple board
logic systems is that the total supply current
taken at 5V can become excessive, causing
voltage drops and noise in the power supply
wiring unless heavy cables and large decoupling
capacitors are used. A convenient solutionto this
problem is to provide power using a higher
voltage supply locally regulated to 5V. Voltaga
drops and noise are now eliminated by the
regulators but they introduce a new problem of
significantly increased power Iossas if standard
regulatom are used. By employing ZLD0500’S as
the local regulators in a circuit similar to the low
voltage battery pack regulator but repeated on
each logic board, the power supply to the logic
boards can be distributed at a voltage close to
5V. This will largely eliminating the added losses
of a distributed power supply system yet still
eliminating the supply voltage errors and
reducing noise.
5). Over Temperature Shutdown
The ZLD0500 regulator includes an over
temperature shutdown circuit that disables the
regulator if its chip temperature should exceed
125°C for any reason. Although intended to
provide a limited guard against excessive
internal power dissipation, this circuit will shut
down the regulator if “W ambient rises above
125”C. Thus, the regulator could be used to
dieable a circuit in the event of the ambient
temperature within which the circuit is mounted
becoming too high. Any internal power
dissipation caused as a result of supplying load
current, will reduce the ambient temperature at
which shutdown occurs. Note that to achieve the
extremely low dropout voltage and high current
performance provided by the ZLD0500 devices,
the parts can be damaged by sustained output
shorts or excessive loads when combined with
high input supply voltages. To ensure reliable
operation, keep loads within the SOA graph
boundaries
indicated in the typical
characteristics.
