DESCRIPTION:

The MSK 5820RH is a rad hard fixed linear regulator capable of delivering 5.0 amps of output current. Typical

dropout is only 0.22 volts with a 2.5 amp load. An external shutdown function is ideal for power supply sequencing.

This device also has internal latching overload protection. The MSK 5820RH is radiation hard and specifically de-

signed for space/satellite applications. The device is packaged in a hermetically sealed space efficient 5 pin SIP that

is electrically isolated from the internal circuitry allowing for direct heat sinking.

APPLICATION NOTES

PIN FUNCTIONS

VIN-

This pin provides power to all internal circuitry in-

cluding bias, start-up, thermal limit and overcurrent latch.

Input voltage range is 2.9V to 6.5V.

GND -

Internally connected to ground, this pin should be

connected externally by the user to the circuit ground.

SHUTDOWN -

There are two functions to the SHUTDOWN

pin. It may be used to disable the output voltage or to

reset a current latch condition. To activate the shutdown/

reset functions the user must apply a voltage greater than

1.6V to the SHUTDOWN pin. The output voltage will turn

on when the SHUTDOWN pin is pulled below the thresh-

old voltage. If the SHUTDOWN pin is not used, it should

be connected to ground. It should be noted that with the

shutdown pin tied to ground, a current latch condition

can only be reset by cycling power off, then on.

VOUT -

This is the output pin for the device.

OVERCURRENT LATCH

Overcurrent protection is provided by the MSK 5820RH

series through the use of a timed latch off circuit. The

internal latch timeout is triggered by an overcurrent con-

dition. To allow for start up surge currents, the timeout is

approximately 5.5mS at 25°C. If the overcurrent condi-

tion remains at the end of the timeout cycle, the regulator

will latch off until the latch is reset. Reset the latch by

pulling the shutdown pin high or cycling VIN off then back

on. A thermal limit condition will trigger the latch with no

time out delay.

FIGURE 1

CURRENT LIMIT AND SOA

The MSK 5820RH current limit function is directly af-

fected by the input and output voltages. Figure 1 illus-

trates the relationship between VIN and I

for various

output voltages. It is very important for the user to con-

sult the SOA curve when using input voltages which re-

sult in current limit conditions beyond 4.5 Amps. When

using input voltages which result in current limit above

4.5 Amps, the user must maintain output current within

the SOA curve to avoid damage to the device. Note that 5

Amp maximum is due to current carrying capability of the

internal wirebonds.

INPUT POWER SUPPLY BYPASSING

To maximize transient response and minimize power sup-

ply transients it is recommended that two 47 F tantalum

capacitors are connected between VIN and ground. A

0.1 F ceramic capacitor should also be used for high fre-

quency bypassing. See typical application circuit.

REPLACING THE OMR9601/IRUH33P253AIM

When the MSK 5820-2.5RH is used as a replacement

for the IR OMR9601 or IRUH33P253B, the user should

recognize that the MSK 5820-2.5RH does not contain in-

ternal tantalum capacitors on the input and output.

OUTPUT CAPACITOR SELECTION

Low ESR output capacitors are required to maintain regu-

lation and stability. Four CWR29FB227 (AVX PN

TAZH227K010L) tantalum capacitors in parallel with ce-

ramic decoupling capacitors (0.1 F typical) provides suf-

ficient gain and phase margin for most applications. The

maximum ESR specification for the CWR29FB227 capaci-

tor is 180mΩ at 100kHz and is sufficient for many appli-

cations. MSK has found through full WCCA that screen-

ing for a maximum ESR of 57mΩ ensures EOL stability

criteria to be met for many applications with the most

stringent requirements. The typical ESR of the

TAZH227K010L from AVX is 49mΩ . Analysis of the fi-

nal design is recommended to ensure stability require-

ments are met.

START UP CURRENT

The MSK 5820RH sinks increased current during startup

to bring up the output voltage. Reference the "Saturated

Drive Current vs. Input Voltage" graph in the typical per-

formance curves of this data sheet and the "Understand-

ing Startup Surge Current With MS Kennedy's RH1573

Based Rad Hard LDO Regulators" application note in the

application notes section of the MS Kennedy Web site for

more information.

APPLICATION NOTES CONT.

THERMAL LIMITING

The MSK 5820RH control circuitry has a thermal shut-

down temperature of approximately 150°C. This ther-

mal shutdown can be used as a protection feature, but

for continuous operation, the junction temperature of the

pass transistor must be maintained below 150°C. Proper

heat sink selection is essential to maintain these condi-

tions. Exceeding the thermal limit activates the latch fea-

ture of the MSK 5820RH. Toggle the shutdown pin high

them low or cycle power to reset the latch. See shut-

down pin description and overcurrent latch description

for more information.

TYPICAL APPLICATIONS CIRCUIT

HEAT SINK SELECTION

ing formula for convective heat flow may be used.

generated for all radiation testing performed by MS

Kennedy. These curves show performance trends

UCTS section on the MSK website.

junction temperature of no more than 125°C.
