Device description
The RHFL4913 adjustable voltage regulator contains a PNP type power element controlled
by a signal resulting from an 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.
6.1
6.2
6.3
ADJ pin
The load output voltage feedback comes from an external resistor divider bridge mid-point
connected to the ADJ pin (allowing all possible output voltage settings as per user
requirements) established between load terminals.
Inhibit ON-OFF control
By setting the INHIBIT pin TTL high, the device switches off the output current and voltage.
The device is ON when the INHIBIT pin is set low. Since the INHIBIT pin is pulled down
internally, it can be left floating in cases where the inhibit function is not used.
Overtemperature protection
A temperature detector internally monitors the power element junction temperature. The
device turns off when a temperature of approximately 175 °C is reached, returning to ON
mode when back to approximately 135 °C. Combined with the other protection blocks, the
device is protected from destructive junction temperature excursions in all load conditions. It
should be noted that when the internal temperature detector reaches 175 °C, the active
power element can be as high as 225 °C. Prolonged operation under these conditions far
exceeds the maximum operating ratings and device reliability cannot be guaranteed.
6.4
Overcurrent protection
An internal non fold-back short circuit limitation is set with I
> 3.8 A (V is 0 V). This
O
SHORT
value can be decreased via an external resistor connected between the I and V pins, with
SC
I
a typical value range of 10 kΩto 200 kΩ. To maintain optimal V regulation, it is necessary to
O
set I
1.6 times greater than the maximum desired application I . When I reaches
SHORT
O O
I
– 300 mA, the current limiter overrules the regulation, V starts to drop and the OCM
SHORT
O
flag is raised. When no current limitation adjustment is required, the I pin must be left
SC
unbiased (as it is in 3 pin packages).
6.5
OCM pin
The OCM pin goes low when the current limit becomes active, otherwise V
= V . It is
I
OCM
buffered and can sink 10 mA. The OCM pin is internally pulled up by a 5 kΩ resistor.

Alternatives to the RHFL4913
The adjustable RHFL4913 is recommended to replace all industry positive voltage
regulators due to its exceptional radiation performance. To replace 3-terminal industry
devices, the fixed voltage versions of the RHFL4913 should be used.
9/19
Application information
RHFL4913
7
Application information
To adjust the output voltage, the R2 resistor must be connected between the V and ADJ
O
pins. The R1 resistor must be connected between ADJ and ground. Resistor values can be
derived from the following formula:
V = V
(R1+ R2) / R1
O
ADJ
The V
is 1.23 V, controlled by the internal temperature-compensated band gap block.
ADJ
The minimum output voltage is therefore 1.22 V and minimum input voltage is 3 V.
The RHFL4913 adjustable is functional as soon as the V - V voltage difference is slightly
I
O
above the power element saturation voltage. The adjust pin to ground resistor value must
not be greater than 10 kΩ, in order to keep the output feedback error below 0.2%. A
minimum of 0.5 mA I must be set to ensure perfect no-load regulation. It is advisable to
O
dissipate this current into the divider bridge resistor. All available V pins, as well as all
I
available V pins, should always be externally interconnected, otherwise the stability and
O
reliability of the device cannot be guaranteed. The inhibit function switches off the output
current electronically, and therefore very quickly. According to Lenz’s Law, external circuitry
reacts with LdI/dt terms which can be of high amplitude in case somewhere a serial coil
inductance exists. Large transient voltage would develop on both device terminals. It is
advisable to protect the device with Schottky diodes to prevent negative voltage excursions.
In the worst case, a 14 V Zener diode could protect the device input. The device has been
designed for high stability and low dropout operation. Therefore, tantalum input and output
capacitors with a minimum 1 µF are mandatory. Capacitor ESR range is from 0.5 Ω to over
20 Ω. This range is useful when ESR increases at low temperature. When large transient
currents are expected, larger value capacitors are necessary.
In the case of high current operation with short circuit events expected, caution must be
exercised with regard to capacitors. They must be connected as close as possible to the
device terminals. As some tantalum capacitors may permanently fail when subjected to high
charge-up surge currents, it is recommended to decouple them with 470 nF polyester
capacitors.
Since the RHFL4913 adjustable voltage regulator is manufactured with very high speed
bipolar technology (6 GHz f transistors), the PCB layout must be designed with exceptional
T
care, with very low inductance and low mutually coupling lines. Otherwise, high frequency
parasitic signals may be picked up by the device resulting in system self-oscillation. The
benefit is an SVR performance extended to far higher frequencies.
7.1
7.2
Notes on the 16-pin hermetic package
The bottom section of the 16-pin package is metallized in order to allow the user to directly
solder the RHFL4913 onto the equipment heat sink for enhanced heat removal.
Remote sensing operation
A separate kelvin voltage sensing line provides the ADJ pin with exact load "high potential"
information (see Figure 3) . But variable remote load current consumption induces variable
Iq current (Iq is roughly the I current divided by the h of the internal PNP series power
O
FE
element) routed through the parasitic series line resistor RW2. To compensate for this
10/19
RHFL4913
Application information
parasitic voltage, resistor RW1can be introduced to provide the necessary compensating
voltage signal to the ADJUST pin.
7.3
FPGA power supply lines
Because these devices are very sensitive to V transients beyond a few % of their nominal
DD
supply voltage (usually 1.5 V), special attention must be given by supply lines designers to
mitigate possible heavy ion L4913 disturbances. The worst case heavy ion effect can be
summarized as: the L4913 internal control loop being cut (made open) or short-circuited for
a sub-microsecond duration. During such an event, the L4913 die power element can either
provide excessive current or current supply stoppage to the output (V
) for a duration of
OUT
about one microsecond, after which time the L4913 smoothly recovers to nominal operation.
To mitigate these "transients", it is recommended to implement the L4913 PCB layout as
follows:
●
Minimizing series/parallel parasitic inductances of the PC path
Using a low ESR 47 µF Tantalum V filtering capacitor with a 470 nF ceramic
●
OUT
capacitor in parallel with the former (to reduce dynamic ESR)
●
Inserting a 100-200 nH ferrite core on the V -to-tantalum capacitor wire
OUT
With this implementation, the ELDO simulated worst transient case shows no more than 90
mV deviation from the nominal line voltage value.
