FIXED VOLTAGE REGULATORS

SERIES

FEATURES:

• Ultra Low Dropout Voltage

• Internal Short Circuit Current Limit

• Output Voltages Are Internally Set To ±1% Maximum

• Electrically Isolated Case

• Internal Thermal Overload Protection

• Many Output Voltage Combinations

• Alternate Package and Lead Form Conﬁgurations Available

DESCRIPTION:

The MSK5200 Series oﬀers ultra low dropout voltages on both the positive and negative regulators. This, combined

with the low θJC, allows increased output current while providing exceptional device eﬃciency. Because of the

increased eﬃciency, a small hermetic 5 pin package can be used providing maximum performance while occupying

minimal board space. Output voltages are internally trimmed to ±1% maximum resulting in consistent and accurate

operation. Additionally, both regulators oﬀer internal short circuit current and thermal limiting, which allows circuit

Please consult the factory if alternate output voltages are required.

Input voltage (VIN =VOUT + a speciﬁed voltage) is implied to be more negative than VOUT.

10 Due to current limit, maximum output current may not be available at all values of VIN-VOUT and temperatures.

See typical performance curves for clariﬁcation.

11 The output current limit function provides protection from transient overloads but it may exceed the maximum continuous rating.

Continuous operation in current limit may damage the device.

12 Continuous operation at or above absolute maximum ratings may adversely eﬀect the device performance and/or life cycle.

13 Internal solder reﬂow temp is 180°C, DO NOT EXCEED.

APPLICATION NOTES

BYPASS CAPACITORS:

OVERLOAD SHUTDOWN:

The regulators feature both current and thermal overload

protection. When the maximum power dissipation is not exceeded,

the regulators will current limit slightly above their 3 amp rating.

As the VIN-VOUT voltage increases, however, shutdown occurs

in relation to the maximum power dissipation curve. If the device

heats enough to exceed its rated die junction temperature due to

excessive ambient temperature, improper heat sinking etc., the

regulators also shutdown until an appropriate junction temperature

is maintained. It should also be noted that in the case of an extreme

overload, such as a sustained direct short, the device may not be

able to recover. In these instances, the device must be shut oﬀ

and power reapplied to eliminate the shutdown condition.

For most applications a 47uF, tantalum capacitor should

be attached as close to the regulator's output as possible. This

will eﬀectively lower the regulator's output impedance, improve

transient response and eliminate any oscillations that may be

normally associated with low dropout regulators. Additional

bypass capacitors can be used at the remote load locations to

further improve regulation. These can be either of the tantalum or

the electrolytic variety. Unless the regulator is located very close

to the power supply ﬁlter capacitor(s), a 4.7uF minimum tantalum

capacitor should also be added to the regulator's input. An

electrolytic may also be substituted if desired. When substituting

electrolytic in place of tantalum capacitors, a good rule of thumb

to follow is to increase the size of the electrolytic by a factor of 10

over the tantalum value.

HEAT SINKING:

To determine if a heat sink is required for your application and

if so, what type, refer to the thermal model and governing equation

below.

LOAD REGULATION:

For best results the ground pin should be connected directly to

the load as shown below. This eﬀectively reduces the ground loop

eﬀect and eliminates excessive voltage drop in the sense leg. It is

also important to keep the output connection between the regulator

and the load as short as possible since this directly aﬀects the load

regulation. If 20 gauge wire were used as an example, which has a

resistance of about 0.008 ohms per foot, this would result in a drop

of 8mV/ft at 1Amp of load current. It is also important to follow the

capacitor selection guidelines to achieve best performance. Refer

to Figure 2 for connection diagram.

Governing Equation: Tj = Pd x (Rθjc + Rθcs + Rθsa) + Ta

WHERE

Tj = Junction Temperature

Pd = Total Power Dissipation

Rθj = Junction to Case Thermal Resistance

Rθcs = Case to Heat Sink Thermal Resistance

Rθsa = Heat Sink to Ambient Thermal Resistance

Tc = Case Temperature

Ta = Ambient Temperature

Ts = Heat Sink Temperature

MSK5202 TYPICAL APPLICATION:

Low Dropout Positive and Negative Power Supply

EXAMPLE:

This example demonstrates an analysis where each regulator is at

one-half of its maximum rated power dissipation, which occurs when

the output currents are at 1.5 amps each. The negative regulator

is worst case due to the larger thermal resistance.

Conditions for MSK5202:

VIN = ±7.0V; Iout = ±1.5A

1.) Assume 45° heat spreading model.

2.) Find regulator power dissipation:

FIGURE 1

Pd = (VIN - VOUT)(Iout)

Pd = (7-5)(1.5)

Pd = 3.0W

Avoiding Ground Loops

3.) For conservative design, set Tj = +125°C Max.

4.) For this example, worst case Ta = +90°C.

5.) Rθjc = 4.7°C/W from the Electrical Speciﬁcation Table.

6.) Rθcs = 0.15°C/W for most thermal greases.

7.) Rearrange governing equation to solve for Rθsa:

Rθsa = ((Tj - Ta)/Pd) - (Rθjc) - (Rθcs)

= (125°C - 90°C)/3.0W - (4.7°C/W) - ( 0.15°C/W)

= 6.8°C/W

The same exercise must be performed for the negative regulator.

In this case the result is 6.82°C/W. Therefore, a heat sink with a

thermal resistance of no more than 6.8°C/W must be used in this

application to maintain both regulator circuit junction temperatures

under 125°C.
