Device description  
The RHFL4913 fixed voltage contains a PNP type power element controlled by a signal  
resulting from amplified comparison between the internal temperature compensated band-  
gap cell and the fraction of the desired output voltage value. This fractional value is obtained  
from an internal-to-die resistor divider bridge set by STMicroelectronics. The device is  
protected by several functional blocks.  
5.1  
5.2  
Low pin count package limitations  
Some functions (INHIBIT, OCM, SENSE) are not available due to lack of pins.  
Corresponding die pads are by default connected inside silicon.  
SENSE pin  
The load voltage is applied by a Kelvin line connected to SENSE pin: Voltage feed-back  
comes from the internal divider resistor bridge. Therefore possible output voltages are set  
by manufacturer mask metal options. SENSE pin is not available in 3pin packages.  
5.3  
5.4  
Inhibit ON-OFF control  
By setting INHIBIT pin TTL-high, the device switches off the output current and voltage. The  
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. INHIBIT pin is not available in 3pin  
packages.  
Overtemperature protection  
A temperature detector internally monitors the power element junction temperature. The  
device goes OFF at approx. 175 °C, returning to ON mode when back to approx. 40 °C. It is  
worth noting that when the internal temperature detector reaches 175 °C, the active power  
element can be at 225 °C: device reliability cannot be granted in case of extensive operation  
under these conditions.  
5.5  
Overcurrent protection  
I
pin. An internal non-fold back short-circuit limitation is set with I  
> 3.8 A (V is 0  
SC  
SHORT O  
V). This value can be reduced by an external resistor connected between I pin and V pin,  
SC  
I
with a typical value range of 10 kΩ to 200 kΩ. This adjustment feature is not available in 3  
pin packages. To keep excellent V regulation, it is necessary to set I  
1.6 times  
O
SHORT  
greater than the maximum desired application I . When I reaches I  
– 300 mA, the  
O
O
SHORT  
current limiter overrules regulation and V starts to drop and the OCM flag is risen. When no  
O
current limitation adjustment is required, I pin must be left unbiased (as it is in 3 pin  
SC  
packages).

packages.

Alternate to  
RHFL4913 fixed (& custom) voltages replace all 3-terminal industry devices, providing  
essential benefits  
- Lower drop-out  
- High radiation performance  
- Better SVR  
- Saving the high stability external setting resistors.

Application information  
RHFL4913XX15 - RHFLXX25 - RHFLXX33 - RHFLXX50  
6
Application information  
The RHFL4913 fixed voltage is functional as soon as V -V voltage difference is slightly  
I
O
above the power element saturation voltage. A minimum 0.5 mA I ensures perfect “no-  
O
load” regulation.  
All available V pins must always be externally interconnected, same thing for all available  
I
V pins, otherwise device stability and reliability cannot be granted. All NC pins can be  
O
connected to ground. 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 some series-inductance exists. The effect would be  
a large transient voltage developed on both device terminals. It is necessary to protect the  
device with Schottky diodes preventing negative voltage excursions. In the worst case, a 14  
V Zener diode shall protect the device input.  
The device has been designed for high stability and low drop out operation: minimum 1 µF  
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 470 nF polyester  
capacitors.  
Being RHFL4913 fixed voltage manufactured with very high speed bipolar technology 6 GHz  
f transistors), the PCB lay-out must be performed with extreme care, very low inductance,  
T
low mutually coupling lines, otherwise high frequency parasitic signals may be picked-up by  
the device resulting into self-oscillation. User’s benefit is a SVR performance extended to far  
higher frequencies.  
6.1  
Remote sensing operation  
In case the load is located far from the regulator, it is recommended to comply with the  
scheme below. To obtain the best regulation, it is in addition essential to care about:  
– The wire connecting R2 to the load end must not be crossed by the load current  
(Kelvin sense).  
The noise captured by the wires between the load and the chip could bring a noisy output  
voltage. In case this happens, it is recommended that shielded cables are used for these  
connections. The external wrap must be used for connecting the ground of the chip with the  
load ground. It is also recommended to place 1 µF tantalum capacitors between output and  
ground close to the device and another next to the load.
