Device description

Device description
The RHFL4913 Adjustable contains a PNP type power element controlled by a signal resulting from
amplified comparison between the internal temperature compensated Band-Gap and the fraction of the
desired Output Voltage value obtained from an external resistor divider bridge. The device is protected by
several functional blocks.
4.1
ADJ Pin
The Load output voltage feed-back comes from an external divider resistor bridge middle point connected
to ADJ pin (allowing all possible output voltage settings as per User’s desire) established between Load
terminals.
4.2
INHIBIT ON-OFF Control
By setting INHIBIT pin TTL-High, the Device switches off the Output Current and Voltage. Device is ON
when INHIBIT pin is set Low. Since INHIBIT pin is internally pulled down, it can be left floating in case
Inhibit function is not utilized.
4.3
Overtemperature protection
A temperature detector internally monitors the power element junction temperature. The Device goes
OFF when approx. 175°C are reached, returning to ON mode when back to approx. 40°C. Combined with
other protection blocks, it protects the Device from destructive junction temperature excursions in all load
conditions. It is worth noting that when internal temperature detector reaches 175°C, the active power
element can be at 225°C: Extensive operation under these conditions far exceeds Maximum Operation
Ratings and Device reliability cannot be granted.
4.4
Overcurrent protection
An internal non-fold back Short-Circuit limitation is set with ISHORT > 3.8A (VO is 0V). This value can be
downward modified by an external resistor connected between ISC and VI pins, with a typical value range
of 10kΩ to 200kΩ. To keep excellent VO regulation, it is necessary to set ISHORT 1.6 times greater than the
maximum desired application IO. When IO reaches ISHORT – 300mA, the current limitor overrules
Regulation and VO starts to drop and OCM flag is risen. When no current limitation adjustment is
required, ISC pin must be left unbiased (as it is in 3pin packages).
4.5
OCM pin
Goes Low when current limit starts to be active, otherwise VOCM = VI. It is buffered and can sink 10mA.
OCM pin is internally pulled-up by a 5 kΩ resistor.
4.6
Alternates to
RHFL4913 is recommended to replace all Industry Positive Regulators due to its exceptional Radiation
performance. To replace 3-terminal Industry devices, use RHFL4913 Fixed Voltage versions.

Application information
RHFL4913 ADJUSTABLE VERSION
5
Application information
Adjusting Output Voltage: R2 resistor must be connected between VO and ADJ pins. R1 resistor must be
connected between ADJ and Ground. Resistor values can be derived from the following formula:
VO = VADJ (R1+ R2) / R1
VADJ is 1.23V, controlled by the internal temperature compensated Band Gap block.
The minimum Output voltage is therefore 1.22V and minimum Input voltage is 3V.
The RHFL4913 Adjustable is functional as soon as VI - VO voltage difference is slightly above the power
element saturation voltage. The Adjust pin to Ground resistor must not be bigger than 10kΩ to keep the
output feed-back error below 0.2%. A minimum 0.5mA IO must be set to ensure perfect “no-load”
regulation. It is advisable to dissipate this current into the divider bridge resistor. All available VI pins shall
always be externally interconnected, same thing for all available VO pins, otherwise Device stability and
reliability cannot be granted. The INHIBIT function switches off the output current in an electronic way,
that is very quickly. According to Lenz’s Law, external circuitry reacts with LdI/dt terms which can be of
high amplitude in case somewhere an inductance exists. Large transient voltage would develop on both
Device terminals. It is advisable to protect the Device with Schottky diodes preventing negative voltage
excursions. In the worst case, a 14V Zener diode shall protect the Device Input. The Device has been
designed for high stability and low drop out operation: Minimum 1µF input and output tantalum capacitors
are therefore mandatory. Capacitor ESR range is from 0.5 Ω to over 20 Ω. Such range turns out to be
useful when ESR increases at low temperature. When large transient currents are expected, larger value
capacitors are necessary.
In case of high current operation with expected short-circuit events, caution must be considered relatively
to capacitors. They must be connected as close as possible to device terminals. As some tantalum
capacitors may permanently fail when submitted to high charge-up surge currents, it is recommended to
decouple them with 470nF polyester capacitors.
Being RHFL4913 Adjust manufactured with very high speed bipolar technology (6GHz fT transistors), the
PCB layout must be performed with exceptional care, very low inductance, low mutually coupling lines,
otherwise high frequency parasitic signals may be picked-up by the Device resulting into system
oscillation. The benefit is an SVR performance extended to far higher frequencies.

Notes about 16pin hermetic package
The bottom section of 16pin packages is metallized in order to allow User to directly solder the
RHFL4913A on the equipment heat sink for enhanced heat removal.
5.2
Remote sensing operation
See Figure 2. A separate Kelvin Voltage sensing line provides ADJ pin with exact Load "high potential"
information. But variable remote Load current consumption induces variable Iq current (Iq is roughly the
IO current divided by the hFE of the internal PNP series power element) routed through parasitic series
line resistor symbolized as RW2. To compensate this parasitic voltage, the Resistor RW1 introduced on
purpose provides the necessary compensating voltage signal to ADJust pin.
