Features
General Description
• Low power consumption
The HT75xx-7 is a low power high voltage series of
regulators implemented in CMOS technology which
has the advantages of low voltage drop and low
quiescent current. They allow input voltages as high
as 30V and are available with several fixed output
voltages ranging from 2.1V to 12.0V.
• Low voltage drop
• Low temperature coefficient
• High input voltage – up to 30V
• Output voltage accuracy: tolerance ±2%
• Over current protection
When the CE input is low, a fast discharge path pulls
the output voltage low via an internal pull-down
resistor. An internal over-current protection circuit
prevents the device from damage even if the output
is shorted to ground. An over-temperature protection
circuit ensures the device junction temperature will
not exceed a temperature of 160°C.
• Over temperature protection
• Chip enable/disable function
• 3-pin SOT89 and 5-pin SOT23 packages
Applications
• Battery-powered equipment
• Communication equipment
• Audio/Video equipment

Application Information
Power Dissipation Calculation
When using the HT75xx-7 regulators, it is important
that the following application points are noted if
correct operation is to be achieved.
In order to keep the device within its operating limits
and to maintain a regulated output voltage, the power
dissipation of the device, given by P D, must not
exceed the Maximum Power Dissipation, given by
PD(MAX). Therefore PD ≤ PD(MAX). From the diagram it
can be seen that almost all of this power is generated
across the pass transistor which is acting like a
variable resistor in series with the load to keep the
output voltage constant. This generated power which
will appear as heat, must never allow the device to
exceed its maximum junction temperature.
External Circuit
It is important that external capacitors are connected
to both the input and output pins. For the input pin
suitable bypass capacitors as shown in the application
circuits should be connected especially in situations
where a battery power source is used which may have
a higher impedance. For the output pin, a suitable
capacitor should also be connected especially in
situations where the load is of a transient nature, in
which case larger capacitor values should be selected
to limit any output transient voltages.
In practical applications the regulator may be called
upon to provide both steady state and transient
currents due to the transient nature of the load.
Although the device may be working well within its
limits with its steady state current, care must be taken
with transient loads which may cause the current to
rise close to its maximum current value. Care must
be taken with transient loads and currents as this will
result in device junction temperature rises which must
not exceed the maximum junction temperature. With
both steady state and transient currents, the important
current to consider is the average or more precisely
the RMS current which is the value of current that will
appear as heat generated in the device. The following
diagram shows how the average current relates to the
transient currents.
Thermal Considerations
The maximum power dissipation depends on the
thermal resistance of the package, the PCB layout,
the rate of the surrounding airflow and the difference
between the junction and ambient temperature. The
maximum power dissipation can be calculated using
the following formula:
PD(MAX) = (TJ(MAX) – Ta) / θJA
where TJ(MAX) is the maximum junction temperature,
Ta is the ambient temperature and θJA is the junctionto-ambient thermal resistance of the IC package in
degrees per watt. The following table shows the θJA
values for various package types.

Maximum Power Dissipation (W)
For maximum operating rating conditions, the
maximum junction temperature is 150°C. However,
it is recommended that the maximum junction
temperature does not exceed 125°C during normal
operation to maintain an adequate margin for device
reliability. The derating curves of different packages
for maximum power dissipation are as follows:

HT75xx-7
As the quiescent current of the device is very small it can generally be ignored and as a result the input current can
be assumed to be equal to the output current. Therefore the power dissipation of the device, PD, can be calculated as
the voltage drop across the input and output multiplied by the current, given by the equation, PD = (VIN – VOUT) × IIN.
As the input current is also equal to the load current the power dissipation PD = (VIN – VOUT) × ILOAD. However,
with transient load currents, PD = (VIN – VOUT) × ILOAD(AVG) as shown in the figure.
