Application Information (continues)
Adjustable Regulator Design
The adjustable regulator versions (TS39152) is allow
to programming the output voltage anywhere between
1.25 and the 16V maximum operating rating of the
family.
Two resistors are used. Resistors can be quite large
up to 1M
, because of the very high input impedance
and low bias current of the sense comparator, the
resistor values are calculated by:
R1 = R2 * [(Vout / 1.24) – 1]
Where is Vout the desired output voltage. Above
application
circuit
shows
Applications with widely varying load currents may
scale the resistors to draw the minimum load current
required for proper operation.
Error Flag
component
definition.
TS39151 versions feature an Error Flag, which looks
at the output voltage and signals an error condition
when this voltage drops 5% below its expected value.
The error flag is an open-collector output that pulls low
under fault conditions. It may sink 10mA. Low output
voltage signifies a number of possible problems,
including an over-current fault (the device is in current
limit) and low input voltage. The flag output is
inoperative
during
over
conditions.
Enable Input
temperature
shutdown
TS39151 and TS39152 versions feature an enable
(EN) input that allows ON/OFF control of the device.
Special design allows “zero” current drain when the
device is disabled–only microamperes of leakage
current flow. The EN input has TTL/CMOS compatible
thresholds for simple interfacing with logic, or may be
directly tied to
≤
20V. Enabling the regulator requires
approximately 30uA of current.
