Pulse-testing techniques maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be
taken into account separately.
Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input
Due to the dropout voltage and output current-limiting characteristics of this device, output current is limited to less than 700 mA at
input-to-output voltage differentials of less than 25 V.

8 Detailed Description
8.1 Overview
The TL783 device is an adjustable three-terminal high-voltage regulator with an output range of 1.25 V to 125 V
and a DMOS output transistor capable of sourcing more than 700 mA. It is designed for use in high-voltage
applications where standard bipolar regulators cannot be used. Excellent performance specifications, superior to
those of most bipolar regulators, are achieved through circuit design and advanced layout techniques.
As a state-of-the-art regulator, the TL783 device combines standard bipolar circuitry with high-voltage doublediffused MOS transistors on one chip, to yield a device capable of withstanding voltages far higher than standard
bipolar integrated circuits. Because of its lack of secondary-breakdown and thermal-runaway characteristics
usually associated with bipolar outputs, the TL783 maintains full overload protection while operating at up to
125 V from input to output. Other features of the device include current limiting, safe-operating-area (SOA)
protection, and thermal shutdown. Even if ADJ is disconnected inadvertently, the protection circuitry remains
functional.
Only two external resistors are required to program the output voltage. An input bypass capacitor is necessary
only when the regulator is situated far from the input filter. An output capacitor, although not required, improves
transient response and protection from instantaneous output short circuits. Excellent ripple rejection can be
achieved without a bypass capacitor at the adjustment terminal.

The TL783 acts as a high-voltage adjustable regulator. The device works to keep the voltage at the OUT pin 1.25
V higher than the voltage at the ADJ pin. Therefore, a resistor divider can be used to set the output voltage.

SLVS036N – SEPTEMBER 1981 – REVISED JANUARY 2015
Typical Application (continued)
9.2.2 Detailed Design Procedure
The internal reference (see Simplified Schematic) generates 1.25 V nominal (Vref) between OUT and ADJ. This
voltage is developed across R1 and causes a constant current to flow through R1 and the programming resistor
R2, giving an output voltage of:
VO = Vref (1 + R2 / R1) + lI(ADJ) (R2)
or
VO ≉ Vref (1 + R2 / R1)
The TL783 was designed to minimize the input current at ADJ and maintain consistency over line and load
variations, thereby minimizing the associated (R2) error term.
To maintain II(ADJ) at a low level, all quiescent operating current is returned to the output terminal. This quiescent
current must be sunk by the external load and is the minimum load current necessary to prevent the output from
rising. The recommended R1 value of 82 Ω provides a minimum load current of 15 mA. Larger values can be
used when the input-to-output differential voltage is less than 125 V (see the output-current curve in Figure 12) or
when the load sinks some portion of the minimum current.
9.2.2.1 Bypass Capacitors
The TL783 regulator is stable without bypass capacitors; however, any regulator becomes unstable with certain
values of output capacitance if an input capacitor is not used. Therefore, the use of input bypassing is
recommended whenever the regulator is located more than four inches from the power-supply filter capacitor. A
1-μF tantalum or aluminum electrolytic capacitor usually is sufficient.
Adjustment-terminal capacitors are not recommended for use on the TL783 because they can seriously degrade
load transient response, as well as create a need for extra protection circuitry. Excellent ripple rejection presently
is achieved without this added capacitor.
Due to the relatively low gain of the MOS output stage, output voltage dropout may occur under large-load
transient conditions. The addition of an output bypass capacitor greatly enhances load transient response and
prevents dropout. For most applications, it is recommended that an output bypass capacitor be used, with a
minimum value of:
Co (μF) = 15 / VO
Larger values provide proportionally better transient-response characteristics.

Typical Application (continued)
9.2.2.2 Protection Circuitry
The TL783 regulator includes built-in protection circuits capable of guarding the device against most overload
conditions encountered in normal operation. These protective features are current limiting, safe-operating-area
protection, and thermal shutdown. These circuits protect the device under occasional fault conditions only.
Continuous operation in the current limit or thermal shutdown mode is not recommended.
The internal protection circuits of the TL783 protect the device up to maximum-rated VI as long as certain
precautions are taken. If Vl is switched on instantaneously, transients exceeding maximum input ratings may
occur, which can destroy the regulator. Usually, these are caused by lead inductance and bypass capacitors
causing a ringing voltage on the input. In addition, when rise times in excess of 10 V/ns are applied to the input,
a parasitic npn transistor in parallel with the DMOS output can be turned on, causing the device to fail. If the
device is operated over 50 V and the input is switched on, rather than ramped on, a low-Q capacitor, such as
tantalum or aluminum electrolytic, should be used, rather than ceramic, paper, or plastic bypass capacitors. A Q
factor of 0.015, or greater, usually provides adequate damping to suppress ringing. Normally, no problems occur
if the input voltage is allowed to ramp upward through the action of an ac line rectifier and filter network.
Similarly, when an instantaneous short circuit is applied to the output, both ringing and excessive fall times can
result. A tantalum or aluminum electrolytic bypass capacitor is recommended to eliminate this problem. However,
if a large output capacitor is used, and the input is shorted, addition of a protection diode may be necessary to
prevent capacitor discharge through the regulator. The amount of discharge current delivered is dependent on
output voltage, size of capacitor, and fall time of Vl. A protective diode (see Figure 21) is required only for
capacitance values greater than:
Co (μF) = 3 × 104 / (VO)2
Care always should be taken to prevent insertion of regulators into a socket with power on. Power should be
turned off before removing or inserting regulators.

Typical Application (continued)
9.2.2.3 Load Regulation
The current-set resistor (R1) should be located close to the regulator output terminal, rather than near the load.
This eliminates long line drops from being amplified, through the action of R1 and R2, to degrade load regulation.
To provide remote ground sensing, R2 should be near the load ground.

10 Power Supply Recommendations
A decoupling capacitor is needed on the IN pin of the TL783 if the TL783 is more than 4 inches from its power
supply's filter capacitor. The differential input and output voltage levels are detailed in Recommended Operating
Conditions.
11 Layout
11.1 Layout Guidelines
Input and output traces should be thick enough to handle desired currents, which can reach up to 700 mA on the
output. ADJ pin traces can be smaller because the adjustment current is negligible.

12.1 Trademarks
All trademarks are the property of their respective owners.
12.2 Electrostatic Discharge Caution
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
